You need to understand that winning long term isn’t in our hands. Winning completely depends on our luck, and sadly we cannot control the luck. No skill or strategy helps you to win the games. It’s just pure luck and nothing else. Now on the other hand, we can control ourselves from extreme gambling. So practically, if we see it, then definitely self-control is possible. One just needs to set gambling budgets and only gamble when there is the highest possibility of making money.
