Casinos need to be profitable to keep running, and that's what most gamblers are calling not provably fair, because the provably fair they wanted is winning more and losing less, people got to think for themselves and most of the times this makes them greedy without them even knowing it.
Provably fair is something that casinos decides themselves, it is not the same provably fair that gamblers truly wants, you can't eat your cake and have it at the same time, it's impossible.
I will agree with you on that regard of maintenance because if them losses more than gambler the casinos may shutdown, evry business target is to make profit and remain functionality, likewise the gambler many who claimed they engaged for fun may be deceiving themselves as far I know more than 75 percentage of gambler is basically for profit,the reason the clamour for irregularities in casino site is when their losses is more than wining you hardly hear gambler cried out when his wining more. Every game that seem fair have area it affects the casino, I have engaged on game where a minute to the finishing of the game amount great losses after seeing my wining, if dig deep it show that casino is lossing and need strategy to recover their losses by applying some magic through dia minutes.
I think that nowadays, when most casinos operate online, AI and casino software can fully control how the casino generates its profit. In other words, the program already has a predetermined percentage of wins and losses built into it. The casino is supposed to take a certain percentage of profit from the overall pool, while everything else, who wins and how much each player wins, is based on random probability for the players. So, in that sense, there can indeed be a fair probability for the players, but only after taking the casino’s profit margin into account.
