Also useful to circumvent iOS's sorry state of ad blocking. I use an ad blocker on my device, too, but the pi-hole takes care of 90% of the stuff that annoys me.
I've donated a few times; consider buying the devs a cup of coffee!
Using someone else's device and off my network is entirely scary.
But, pro-tip, use a machine that has an ssd (or other real) drive. Having your network DNS go down because of a bad or corrupted sd card will drive you bonkers.

If you don't want to do that and keep their gateway, I'd expect you can run pi-hole anyway, and if you're not getting the behavior you want (e.g., the gateway seems to be intercepting dns or something), you can try DNS-over-HTTPS.
That said a better router is usually worth it, I like my Netgear Nighthawk because I'm a bit lazy, someone else probably has a better suggestion.
This is totally right, and that is how I have my network configured. I have a firewall behind a dumb cable modem, and I set the DNS server for the network on that device. When machines configure w/ DHCP, they get assigned the router's address for dns resolution, which then delegates to the pi-hole. That's all specific to my hardware though.
Depending on the details, it can go from plugging your fibre directly into a small factor PC, to not being able to do it because even bridging is not available on the box and everything is proprietary.
I for instance replaced the shitty Livebox 3 from my French provider Orange with a PC running Debian. Before that it was a Ubiquity Edge Router 4.
Orange make it difficult to change the device, but not impossible. I would love them to just provide my IP though a standard authenticated DHCP request.
I've seen this said many times, and it matches my experience as well. But why should an SSD be more reliable than an SD card when the underlying technology (flash memory) is identical? Or is it not identical? Or it is due to the more sophisticated controller of an SSD?
But anyway, i still have a spare rasbpi lying around somewhere…
The payoff (usable, perhaps even enjoyable, internet) is worth any admin it might create.
