I switched to Linux and have no issues with gaming. There are a couple of settings that need tweaked in steam, but it doesn’t take a computer genius to figure it out, just follow a guide or video.
For a beginner something like Mint might be the easiest transition. I went with Garuda myself, and it’s worked well, but I feel it’s probably a little less intuitive that something like Mint.
For gaming, look into proton, and how to have your games run with it and you’ll probably be fine. Keep your windows key on hand in case you decide to revert.
