Family members for me, but they don't understand the difference between the windows search box in the task bar (next to the "start" button), and google. The difference between Chrome and google.com is lost on them as well.

It's a good exercise in patience for me while we go through the steps of describing the differences between searching for things on your computer vs searching for things on the internet, what google is, etc.

They've been using the internet since I was a kid in the 90's.

I'm sure most of us have examples of this in our lives, being the de-facto "computer person" in the family. It is what it is at this point. For whatever reason, if you didn't grow up with computers, it's incredibly difficult to understand them as an adult. Which still applies to huge swaths of the worlds population.
