It greatly depends on the type of games you play, the vast majority of things I play I just hit play on Steam and that's it. Sure I had to do some setup, i.e. install Proton-GE and set Steam to use it as default for all games, otherwise only some games that Valve tested are available, but all in all it's almost 0 setup.

That being said that's been true for years, so I doubt that if you had a bad experience in 2021 it's going to be much different now. Also you need to realise that not even Windows is out of the box, you had to install drivers and programs, PCs are not consoles and with customisability comes the need to setup. And even though you don't have interest in the technical part of Linux you'll need to learn some of it, just like you did for Windows, and most importantly you'll need to forget the technical parts you know of windows that are different on Linux, that's usually one of the biggest problems I see, people trying to use Linux as if it were Windows and having a bad time.
