They’re surprisingly powerful for all three games that are available on the platform.

Jokes aside, there are some games with competent Mac ports and if you only have an M-series Mac, you can find some titles that play nice. But most of the stuff that you’d play on a PlayStation or on Windows is simply not available.

But the gaming software market is very heavily biased towards delivering for Windows on Intel. That said, I’m not a gamer so what do I know?

The processing power is there but the actual game support is not, which is the more important part. There are some games that support it but at least 3/4th of my Steam library won't run on a macbook.

Even games which used to run on mac mostly stopped after 32bit support was killed.

I'd like to meet the person that supposed this to you, and ask them what games they play.
