I don't think the Steam hardware survey is representative of the market size. Most people with Macs are accustomed to games that should run just fine on them never getting released, which means there often isn't any point to installing Steam on a Mac in the first place. Therefore they wouldn't be represented even though they are gamers, they spend money, and they have Macs.
I don't have a PC for personal use, but I do have a lot of game consoles, an M1 MacBook Pro, and an M2 Mac mini. There are lots of games like Pizza Tower that look fun to me, do not have a Mac version, but do have a Switch version. So I wind up spending money on Switch games that would've gone to Steam if the publisher had bothered with a macOS release.
While I do have Steam installed on my M1 and M2, I rarely launch it because I've only bought eight games off Steam in two years because of this dynamic, meaning I haven't even participated in the survey myself. My Steam account is over 20 years old and has a healthy library from when I was a PC gamer. I'd say my money's on the table, but my money's in Nintendo's wallet. But I'd really rather be buying macOS versions!
