There is actually no specific trick for you to be successful in gambling because it isn't skill-based but things will only rely on luck. You should know how to handle your funds well and control your urge. Gambling was made for fun so focusing and relying our necessities on it will be a big risk.
Managing funds is very important in gambling because it can minimize the risk of your money so it is very much needed, to be successful in gambling is very difficult I think there are many people playing gambling but there is still no success maybe because of greed and emotional that continues to exist in us so that it is increasingly difficult to succeed.
Luck is rarely found there can only be 1 person who gets it and after that it's hard to find again.
