Proton is based on Wine, when people say Wine in a gaming context, there's a decent chance they just mean Proton. Also there's absolutely no need for gaming distros in this situation, gaming works out of the box on any (semi-normal) distro, the most you'll have to do is flick a switch in Steam.
Edit: Or in this case with the Sims install Lutris I guess, since it's an EA game, but that also isn't much more difficult
