Yeah, casinos are well known to have lots of checks to actually make sure they are not losing money while operating.
Technology always has been there with the potential to win over the casinos, but the casinos always remove your chances to do it.
For example using devices for counting cards, and similar things, cameras and people in the casino are always looking for things like this.
And if you keep winning more than what's expected they keep an eye on you, and eventually you might be invited to leave their premises if you keep winning.
That is why famous casinos always ensure that their casinos can operate well and always make a profit from their business. With the technology that casinos use, they can give casinos the opportunity to make a lot of profit from losing gamblers, so gamblers should be aware that they don't need to chase wins. Casinos will not let gamblers win many games or win big because it will affect their profits. And yes, the casino will not like it if there are gamblers who often win, even if it is an honest win, so the casino may restrict those gamblers who win.
