As others said it’s just a portable pc - there is steam os preinstalled, which has a gaming mode (looks alot like steam big picture mode from pc) and a desktop mode.
Many people install windows because of the compatibility, however I’ve found the compatibility layer (proton) works for 99% of games so I’ve stayed with steamos.
I’ve been able to play any game I’ve played on my windows pc by simply copying the installed files to the deck and running the exe via proton.
