That's absolutely not true, the vast majority of Windows games now run flawlessly on Linux via Proton. This is especially true for the kind of games you can expect to run on such modest hardware, i.e. not AAA games with kernel-level anticheat.
Linux is not even remotely considerable as an option for the average consumer, which is fine and fully intentional with the audience and goals Linux distros serve.
You could even consider this a strong positive, because a Linux distro geared towards average consumers would probably be an analog to Samsung's take on Android. What makes your experience with Linux good is that it isn't catering towards a wider audience.
Linux has twice the number of active Steam users as Mac, with probably very nearly all of them using Proton to some degree: https://store.steampowered.com/hwsurvey/Steam-Hardware-Softw...
Personally, I've actually had noticeably better compatibility on Linux with older games, compared to Windows. And every single one I've been interested in for the past several years works flawlessly on it. (I don't enjoy most AAA games, so my sample is definitely skewed, but it's a fairly common result)
