I'm torn on that. I spent years playing games exclusively on a Mac and didn't feel like I was missing that much. Given how bad the Mac gaming scene was in the 2000's, in the 2010's we've seen an explosion in the number of excellent games coming to Mac from both AAA and indie publishers. Seems like ever since Steam came to macOS, the games have followed.
If gaming is a secondary use of your computer, a Mac isn't quite as bad as people make it out to be. Especially if you enjoy indie games, it seems like all of them run on Mac, and most of them have modest hardware requirements. Example: I play a ton of Rimworld, and it runs exactly the same on my modest Mac and my killer PC. It's mostly AAA titles where you miss out.
I finally got to where I wanted a machine whose primary use would be games, and for that case you're correct, a half-decent PC crushes any Mac on any gaming metric.
