Yeah that's what they need, at minimum. Full transparency.
This trick was used at the Aria in the late 2010s in order to rig lineups for high stakes games. In order to feign "fairness", when a fish would show up, they would take everyone's names to the back and "draw 8 people" to play, as the list would be very long. Coincidentally, the fish was always one of the 8, and the fish's favorite opponents (and other preferred players) would also coincidentally always win. If you weren't part of the in-crowd and/or didn't tip the floorman big, you weren't getting a seat.
