The other distros are split by version, while Arch, being a rolling release is but a single entry. I bet if you add up all of the Ubuntus and Linux Mints, they’d be much higher than Arch.
steam is based on arch so you would have to add those two and then compare and that is 48.7 so all the rest would have to be debian.
by that logic you also have to add Manjaro to Arch at 2.95% which makes it 51.65% Arch, plus I use EndeavorOS which is also based on Arch and not on the list, but I would not be surprised if it broke the 1% userbase for steam.
From the 22% Other: We probably have at least 5% Red Hat based distros like Fedora and Nobara that I hear is popular for gaming.
2-3% might be OpenSuse
I mean I was sorta using your logic. arch is more like debain than ubuntu.
