Correct me if I’m wrong, but don’t most Steam games require the steam client in order to run? You can’t necessarily just copy the files into a flash drive and deliver them to another computer.
(unless of course the game has DRM, in which case both suffer from the same problem)
That’s GOG’s whole schtick, none of the games they sell have DRM when purchased from their store. You can always copy the installer to another computer and run it.
I don’t think there’s a way of checking how many games are like this, but I find that the majority of games I’ve tried doing that just work, and the ones that don’t are mostly bad programming (e.g. crashes trying to load the steam library).

That’s not entirely true, as a general rule I think GoG has a lot less DRM-ed games, but it’s not 100% DRM free like they sometimes claim https://www.gog.com/forum/general/drm_on_gog_list_of_singleplayer_games_with_drm/page1
