We all have our different lucky moment and we are not in the know when we could be lucky to get a win that is why we have to keep trying but it's very important that while we keep trying our luck nonstop we make sure to gamble responsibly and not chasing losses. Keep things normal because being lucky has nothing to do with chasing losses.
The Truth be told, gambling results are quietly unknown to us as a gambler regardless of the level of skills that you think you have developed over the time, you can't predict what the outcome of a game will be and that is why we need to do everything possible to remain in a position where we can acknowledge the place of luck in whatever games that we play.
Anybody can predict the possible outcome of any game in gambling but that question is, how many will be correct with their prediction by the end of day..
So, it's not that we can't predict the outcome of a game, we can predict, but we can't be correct all the time, if we have the power to correctly predict future outcomes of such things as in gambling or sport betting, I believe that..
1. There won't be any casino here because of the obvious
2. Even if casinos exists, it would be a very risky business for those who choose to run a casino because their chances of losing and going bankrupt would be extremely high.
But then, like you have correctly said, luck is the sole determinant of our fate when it comes to gambling, and casinos have a better advantage over the gamblers due to mechanism they apply to their system.
