At least now you know that the dice is might not be the best game for you. You could try other games like poker and other card games. But if you prefer dice games more, you should reevaluate your chances on winning on that. In card games, you can train and have strategies that can minimize your loses. But in dice, nothing will stop you unless you'd emptied your capital.
I would say trying sport betting can increase our chances of making profits compared to pokers or other casino games since we can have some data to analyse the sports,when comes to OP's question there are players who is sitting well at over all profits,we can find those players at the leader board feature on most gambling site but myself not supposed to be on that leader board.
