You say
'I can see some gamers that have more money than busy-time being able to do that'
and in the same paragraph ' Not make broad general sweeping statements lazily'.
Mesa
https://docs.mesa3d.org/relnotes/23.1.7.html
Latest Mesa version in Zorin is 21.2.6 dated Nov 2021. There have been c. 40 versions since then, with the latest being released September 2023. Literally 100s of bug fixes. These can sometimes provide significant improvements.
Halo Infinite couldn't even run on standard amdvlk drivers, so Mesa is/was the only option. That might have changed now but was the case for a long time. Valve/Steam are continuously developing Mesa/RADV drivers, amdvlk aren't as good
With this feature, the shader stutter you would usually see before it's built up in a game should be vastly reduced and so overall we should see smoother gaming performance on Linux with AMD GPUs thanks to this.
'non-LTS is only the way to go if you literally rush out and buy the latest hardware as soon as it is released.'
There are fixes and improvements for my 6700 which was released June 2021 - Hardly 'rushing out to buy latest hardware as soon as its released'
For some enlightenment

there are probably 3 things that make the biggest difference.
Desktop Enviroments (Cinnamon is very bad at gaming for example)
Kernel versions (newer is better)
Driver versions (Mesa / nVidia / AMDVLK / etc, newer is better)
Like I said its a balance, whatever works for you. Zorin may not the best Linux gaming experience, especially on AMD GPUs.
I do agree making broad sweeping statements is lazy, its also condescending
