Yes, when you reach adulthood, you will have the opportunity to look for and get a job and like you said, you will be able to support yourself, albeit not fully, but at least you won't be so dependent on your mother. You say that you're looking for ways to get rich from gambling? I honestly don't believe in this at all, the principle is that gambling was invented just for fun friends and nothing more than that, so don't go too far looking for winnings there, especially if your goal is to get rich quick. Okay, I understand that you'll be using your own money here and won't be using your parents' dependent money, but still we should have a healthier view of gambling.
Lastly, I honestly don't think there's any strategy that can increase the odds of winning, that's just nonsense, and if that were true it would mean a lot of people getting rich but the fact is you probably also know that the rich get poor and the poor get poorer, that's gambling. So the bottom line is don't expect anything from gambling except fun, because it's purely about luck.
I had already passed this stage of my life, I meant that when I reached the age of majority, I could already provide for myself and bet with my own money, and since I earned them myself, I valued them more, because I worked hard and knew their price.
Of course, after some time, I realized that I can’t earn a lot on gambling and I’m unlikely to be able to, or rather, I sometimes managed to earn something, but at work I earned much more, so I didn’t have questions about where I would earn money, but gambling remained fun for me.
