Ubuntu 100%, if you count how many distros are ubuntu based (and collaterally debian based), but I believe it is the most used one even if you only count official ubuntu releases
Maybe arch would be quite high, if you count the steamdeck as desktop (maybe), and the big increase on arch users in the past couple of years (wen’t from being rare to 1 in 3 users saying “I use arch btw”)

In professional work space, ubuntu will probably be highest. Second place I would guess Fedora
As personal workstation I would guess arch (even without steam deck) followed by mint or some flavour of Ubuntu
I don’t think Arch is more used than Ubuntu, unless maybe if you count all the Ubuntu flavors separately
