If the casino dealer is watching over all the operations happening in the casino, he would restrict anybody from cheating the system. Including the owner? not sure, the only confusing thing right now is the relationship between the casino and the game providers. Don't know if the casino would be able to manipulate results from a game provider's server. As these two parties are different and have some restrictions. There are some things a casino can't do with a gaming provider. Take for instance a game provider that can restrict people in a specific location from playing their game, while the casino allows for anybody to use the casino. But, when it comes to that specific game provider the player has no right to participate in such game, except with a VPN. The provably fair system has to do with the casino, not the gaming provider, this is where I don't understand what happens, in terms of the results we get from a casino.
According to research, the casino controls the results, but the provably fair system would still be there to make sure that the house edge allows players some time to win. Hence, it's quite complicated to know the kind of treatment the casino boss or owner would be getting in terms of results. Another common example would be the streamers, we have rumors floating around the gambling niche that streamers get favor from the casino to win more than the players who join the casino to wager games. I think the casino boss would have to decide what happens or for some reason won't derive joy from using his casino. Maybe he'll be interested in other types of games or participate in a higher level of gambling, with top gamblers or fellow casino owners. I always have this feeling that they'll be focused on buying games and helping the bookmaker with football odds to place on some specific teams to maximize profits.
I see that point and it is possible that casino owners can deal it with the provider, just with how we are seeing those streamers who manage to win just for the sake of advertisement and to attract gamers to use the platform, I'm not sure about the set up and if it's really for real I guess it wrecked the purpose of fair gaming.
Though, maybe there's internal setup with this kind of situation and depends from how both the owner and providers negotiation about this adjustment from the gaming system.
Since they work together, you are right, they'll have a way of reaching to an agreement that allows the casino some authority over the results of the game. Atleast to keep the casino from going bankrupt. Running a casino is quite risky, hence if the casino is not in control of the results, players may be winning too many times and running down the funds of the casino. These things happen behind the scenes but still leave the authenticity of provably fair, questioned. Casino promises with the use of provably fair features, the gambler has a transparent result and doesn't have any reason to bother about manipulated results. And the rumors of the streamers have been too real recently, as those wins are becoming more often than any average gambler may have experienced. As for the CEO on second thought, he may not be given any much privilege to receiving a made-up result.
The business is his, so no need for that, I just thought about it from this perspective. A bookseller doesn't need to pay to read his books. But if he's in a book shop he'll buy those books. If the casino owner is playing using his account he can fund his account the same way he does for the streamers. But, if he's playing using a different account to enjoy the fun of gambling, he'll pay to gamble. Because if he's seeing more manipulated results, the owner won't be able to enjoy the fun of gambling. The money he wins still goes back to him as the owner of the casino. So, gambling wouldn't freak such men anymore. That's why in my response, I said that they engage in other activities meant for casino owners. Additionally, they'll be very busy managing the business, handling complaints, and maintaining the authenticity of the casino. Even if they gamble, it won't be on a regular base.
