I'm a gambler and I'm using analysis about the game before i bet. and I call it strategy on gambling. but even if i research alot about that game there's a time that i still losing money because luck is not always on our side. when you're gambling there's no guarantee that you will earn or become rich in gambling. because playing gambling for a long time with out a break it will be the reason for you to become loser.
I have been doing a lot of analysis and then gambling, my analysis usually includes like if i want to bet on Murray vs Djokovic in tennis then I will search google and see who is actually seen better by the market, then I see some predictors pick and then my own knowledge, comparing all I get the best results.
