Steam games that target Linux usually do only target Ubuntu. They work on other distros because Steam bundles a ton of libs internally so that the games use those instead of the host OS's. It's essentially the same situation as if each game was a Docker container with an Ubuntu base image. Also, given the few host OS dependencies that Steam needs are 32-bit libraries, I find it better to not install 32-bit packages and pollute my OS by just running Steam in an Ubuntu container anyway.
