There are outliers where people have gotten banned from casinos for winning too frequently without cheating. This means there is a small chance to hack a winning strategy due to personal skills or a loophole, but the chance of doing it successfully is infinitesimal and if you succeed, it is just a matter of time before casinos restrict you or catch on and fix the bug.
The mindset of trying to game the system is also what makes addicts who lose life savings to gambling.

Basically, everything you said is true. I haven't yet heard of anyone being banned from a casino just for being too lucky. I still think, like you mentioned, that it was more likely a loophole in the system. Also, many casino employees have tried to cheat in some silly ways.
About six months ago, i watched a video about a guy who worked at a casino on the roulette table and managed to find a way to stop the ball on the number he wanted. Of course, his greed gave him away, and he was soon fired and had to return a large sum of money he had "stolen."
So yeah, it's hard to believe anyone has truly succeeded just thanks to luck
