The sure thing is that the casino will find out about people rigging the casino because the casino has a security team that will keep an eye on all the players. The casino will not let people cheat the casino and will find them easily because the security team has access that we can't even imagine. And if the casino finds it, it will surely punish those who cheat by locking their account or even immediately deleting it. In contrast, the casino will take the balance in their account. So you should never think about cheating the casino because you will pay the price later.
You are completely correct; every casino, particularly those with already established legitimate sites, high traffic, and a large number of customers, has security teams inspecting sites to see whether they have been compromised. We are humans, and it is our own personal decision to either embrace or resist cheating when provided or spotted an opportunity to do so, either publicly or discreetly. There is no space for cheating in gambling, and if it occurs, the consequences are usually severe, such as freezing your casino accounts, prohibiting some vital functions such as withdrawals after games, or permanently banning accounts.
We all know that casinos come to make money and not to share money, it is clear that they have thought about this to deal with fraudulent users, for example cheating by taking advantage of bonuses given by casinos or others, they will be ready to arrest anyone who cheats because their system is much more sophisticated than what people think, because of that many cases that are caught on this forum are not strange.
Why do we have to do cheating if indeed we can still win with our strategy and expertise in gambling, I think maybe gamblers who are frustrated and have lost a lot will do things like that in order to be able to return what has been used up because of gambling, so usually that reason makes the most sense .
