Pit people are responsible and have to answer for table games, holds, wins and all that. And they even pass that blame on down the line to dealers. So when a table is constantly underperforming because the pit dude allows some player to win everyday, that pit dude is going to catch some shit. He is not going to be rooting for the player and telling him, "he is the best ever". They are going to find out what is going on, if for no other reason than to save their own ass.
