There's correspondence play which allows engines (or any resource) and certain players which are consistently better at the game under those conditions.

Some of the other players surely try just running Stockfish overnight and taking whatever it says is the best move, and apparently that strategy isn't equally good.

Note that I think the "centaurs" are kind of playing a pretty different game than regular chess: they might have a knack for knowing when a particular engine is weak or strong and then trusting the corresponding engines lines more, or something like that.
