Many console gamers aren't aware of how [well] games play on PC gaming rigs, or they don't care, and are happy to play games on Switch/PS4/PS5/Xbox.
Apple may very well be targeting mobile and console gamers rather than PC gamers with gaming rigs.
Personally I would definitely enjoy playing on a high-end gaming PC (especially as GPUs become easier to find at MSRP), but I already have a Mac and a PS5.
I wouldn't mind more of my Steam library working on macOS though.
