Pretty much. A good coat, scarf, gloves, hat, and long-johns will keep you comfortable outside down to single digits (f).
Plus, when you're outside doing stuff, it can feel pretty warm, even in 20 degree (f) temperatures. One of the best feelings in the world is unzipping my coat on a brisk day while working outside and feeling that cold air hit my hot, sweaty torso.
Also, people adapt to cold pretty quickly. Never-pants people are a thing, even in Russia.
People do complain about the cold though. I bet if you polled people who moved to Texas for Florida, one of their reasons for moving from the north was the weather.
For those who are well enough off, you can even do it with your kids while they are on summer break, which you can't get away with in the winter.
And a lot of folks already "migrate" .. to the beach, to lake houses, etc. Part of it is recreation, but part of it is escaping the heat of landlocked areas.
(N=1:) Friends here in Houston do that to the Upper Peninsula of Michigan every summer.
A few years back, relatives were visiting from the Northeast in July. When planning the visit, they said we should make sure to find some things for them to do that Houstonians do in the summer. I said no problem, we'll take you to Colorado for a month ....
If you're cold? Grab a coat or blanket. Obviously, if you're stuck outdoors exposed to the wind and snow, that's a different thing altogether.
But if you're hot... you have to try and find some shade, drink some water, and hope you don't get heat exhaustion or stroke.
Much easier to bring your body temp up than it is down. That's not even accounting for the psychological effect being hot and miserable does to tempers.
Eh? This is the principle complaint when someone tries to say Minneapolis or Chicago could become the next tech hub. I've lived in both cities.
It's also the chief complaint in Minneapolis for both new transplants and those leaving for greener (pun intended) pastures. In Chicago it's also the first complaint transplants have, but I suppose leavers tend to cite taxes first, weather second.
Jackets can be added for warmth, but only a shower and change of clothes can fix the amount of sweat I experience in the humid heat.
In the heat I can't remove clothing, and even if I largely stay indoors even a 15 minute outdoor walk will require changing and showering.
That said, I can also walk the dog in 0C weather without winter clothing on and feel completely comfortable so we may be outliers :)
Personally, I see far more people saying things like "how can you live there" about cold places, than about hot places (in the US).
However, the majority of the population in the US lives in areas that are less habitable due to cold than they are due to heat. That is to say, a New Yorker or Bostonian readily identifies with needing heat to survive, where they don't as readily identify with needing air conditioning to survive. So, extreme heat is more "foreign", more "other".
Also, in the US, air conditioning is more of a comfort factor than a life-sustaining factor. I mean, sure, there are places in the desert that are only habitable due to A/C, but there are just as many places across the south that are miserable in the summers, but people lived there 100 years ago, all the same.
But as a former Minnesotan.... I can say there is plenty to complain about with respect to cold weather. Joke 1: Minnesota has four seasons, they are called: almost-winter, winter, still-winter, and road-construction. Factoid 1: During grad school at U of M, I had a sticker for a commuter student parking lot only 6 blocks from the EE building. That winter I learned that in a -45F wind chill it takes 4 blocks for your beard to fill with ice, but in a -55F wind chill it only takes 3 blocks. Proverb 1: "There is no such thing as cold weather, only cold clothes." That comes in handy in Minnesota. Related factoid 2: I had a parka that I called my "snow blowing parka" because that is what I wore early in the (still pitch dark) morning to clear out the driveway so that I could get in to work on time. If it was as warm as 0F I never wore it, though, because I would overheat in it if I was working. Got a surprising amount of use out of it. 6 months after moving to California, I found it in my closet and thought to myself: "What the HELL were you thinking, bringing this thing out here?"
So yeah, cold weather in Minnesota is generally somewhere on the not-fun to dangerous end of the spectrum, and layering up is the way to go, with a good dose of thinking ahead. But on the list of reasons I would never move back, cold weather is actually number 3. Number 2 is ridiculous taxes for what you get, number 1 is those infernal deer flies -- think pesky like mosquitoes (the Minnesota state bird) except that every bite takes a chunk of flesh.
I would much prefer to face a cold winter than hot and humid year-round. The weather is the main reason I'll eventually leave Singapore, there's simply nothing you can do to escape the heat/humidity. I work from home and literally run the A/C 24/7, and even then I still never feel "comfortable" (because it's too cold when it's too low, and when it's too high it doesn't evaporate enough sweat).
Also while the summers in Arizona are hot, at least they are not humid. Its a much more easy to tolerate dry heat
And by "hot", it is meant 50C in some places, in which cases planes cannot fly because of density altitude issues:

IIRC, there are cooler places in Arizona as well (mountains?).
Yes. You get snow in the winter in places like Flagstaff.
As someone who really doesn't like humid heat, I still find the low southwestern deserts relatively tolerable (not that you're going to go for a mid-day hike in the summer). That said, if I were to live in that area of the country, I would probably want to be someplace up higher.
As an obese colleague once told me "you can't get more naked than naked, but I can put on as much clothes as needed", in a climatic conversation comparing his midwest origins vs. "hot" SV in California.
