There is absolutely randomness and variance in chess. And variance/randomness is important for any sport, that is what makes it exciting and worth playing. If there were no randomness then every game against the same team and players would be the same.
And anyway, sports are vastly more complicated than chess is. Just simply dribbling a basketball while bipedal walking is beyond the capability of replication by robot at the current moment. But a home computer from 20 years ago would beat >90% of the world in chess.
