This answer is from experience.
Imagine a scenario where you think you are at least as smart as the casino operator, and for the sake of the argument, we agree that you are.
He has the the odds and rules, and the law on his side, you have your money. He has multi-billions of dollars at stake, you have your money, he has thousands of employees on his side, you have your money, he has thousands of years of experience (employees x experience) on his side, you have your money. Feel free to stop me at any point on this trajectory where you think you got what I am saying to you. You simply cannot win.
