There is no easy way to profit when it comes to gambling, all about luck and probabilities. With bigger bank roll the bigger the chance of winning but still not guaranteed to win. Most people here plays dice and lots of people make money by uploading "safe strategies" on youtube to gain referral commissions.
There's indeed no easy way when it comes to gambling and so I don't know if the OP will be able to get what he is actually looking for because everything is based on your luck and skill when it comes to gambling and you don't get lucky all the time so there's no comprehensive answer for the question.
gambling would always about how someone become luck enough to win , the outcome are uncertain and that's what makes the game so excited to be played. if then there's an easy way to get profit from gambling , i'm sure every gambling business would go bankrupt and wouldn't as popular as right now , they keep popping up creating new business in gambling because they know it's easy to take profit from greedy players, not for us.
