However people do see iOS as a gaming market, and soon you can run those apps on a Mac (clearly limitations in interface might restrict it a little). Gaming has many segments. I play WOT on my Mac via Codeweavers emulation, and performance is 60FPS+ in my 2017 iMac in most cases, equivalent to a midrange PC. I am not sure how this will work on M1 however.
To be fair, those gaming markets are almost completely non-overlapping on a venn diagram, and it’s not just the interface (as in user input) that drives that. It’s the form factor. Handheld touchscreen games and many platform/PC games are just drastically different in the interaction models they employ/require, and slapping a touch screen on a MacBook isn’t going to change that meaningfully without many other significant form factor considerations.
