I would only hazard against Debian for gaming because of it’s slower update cycle (yes yes you could use unstable or sid…), so performance improvements or fixes will take longer to get to you.
Otherwise I completely second your comment; OOP, just pick anything mainstream like Ubuntu, Linux Mint, Bazzite, Pop!_OS, you’ll be fine on any of those. Once you’re comfortable with whatever you chose, then you’ll be more informed on picking a distro more suitable for your liking.
There is no “dedicated” one for gaming. Ubuntu Mint, Debian are solid ones. I run Mint MATE personally
