So please answer this question:
How long have you been gambling, and have you already figured out how to win? If yes or no, please explain.
Other games, even if you found out how to make a money for a while, there's a risk involved that pretty much guarantees when it hits that you realize that you haven't "figured out how to win". But just that you were lucky, which was the whole point of gambling. It's not a questio of if the system fails, but when it fails. Majority of people who is making the money with gambling owes that to their luck, and they just want to believe they have found the way, instead of accepting it was luck.
Even in sports betting, it’s always been luck as the primary reason to win, good team work and coordination is only secondary. Know that everything in gambling is about probability, so you have to get lucky and be smart so you can bring home your profits.
