I will go with the first comment, every game is good when you are winning. And we can win on all games, but not always, that's gambling, you can't win all the time, or you can if you have enough patience to wait for red streaks and play big after they pass, but that can be exhausting (I tried that). Of course, we need to have luck, everything depends on your bankroll and gambling style, if you play aggressive you will be close to get busted many times, and you need luck to survive that!
But as you said, we cannot always win because that will depend on luck, and luck will come only to the right person. But I don't think that if we play big, it can help us win because that will only risk our money to get a big loss. Patience will be needed in this game because we don't know when we can win, but the important thing is we can limit the money, so we don't have to lose much money. It is what the gamblers cannot realize, and they still use more money to play without cares about how much they lose. But it is hard to survive in the gambling games because if we only wait for luck comes, that will need too long before we can lose all of the money. So better we stop before it's too late.
