Even against engines, a pro player will often win due to the other player running out of time due to the time loss in every move from copying the engine. You often see the game being slightly equal with the pro player slowly falling behind but then as the time starts to run out for the cheater they completely fall apart.

But those pros will usually make some sort of subtle (because they don't want to openly, straight up accuse unless chess.com has actually banned the opponent after) comment that is clear they think they are playing against a cheater, but the odds are definitely not 1 out of 7. I have been addicted to YouTube chess videos for quite a while now...
