Because some Linux users are so tribal.
I don't even get the idea behind a "gaming" distro. Most major distros can run games just as well. The only difference that I can tell is just that they have Steam and maybe Nvidia's proprietary drivers pre-installed. Something you can do yourself in under a minute after install.
You will have to learn the very simple task of using your package manager to install programs sooner or later anyway and If you can install an OS on your own you can absolutely do the 5 second online search to find the command to install the NVidia proprietary drivers.
To answer your question, yes. Or Mint, or Pop!, or Fedora, or OpenSUSE, or Zorin, or Ubuntu, or Cachy, or many more I'm probably forgetting. They all work. They have their pros and cons that might apply to your specific situation but more likely than not there are multiple good answers for you.
