It seems you haven't quite learned that much yet. The situation ypu have doesn't always happem to experienced gamblers. You can gamble with caution and be responsible with it. Though i'm not a huge fan, gambling the right and responsible way can save you big losses
Why we should bet our money and risk it, even if we know that we will lose our money withing seconds instead we can invest in something else without any big risk, but we decide gambling why? I don't really like gambling its just waste of money and your time you can earn money from other ways too like you can invest in alts you can invest in property etc but Gambling no never.
