Another thing is that if OP find the way to win all dice games, he would become a millionaire which is not the case. Also, the gambling houses won't let you win as they are here to make money. On every loss, OP is increasing the bet and thinks he will win the next bet. In gambling, there will be time when you won't win in a row unless you run out of money and have no option left but to lose everything.
In addition to the fact that the player may run out of money before a winning outcome happens, the gambling house may also simply not accept the next bet and this will ruin the whole strategy. They are here to make money and it is clear that they will do everything to save their money (and get the money of the players). If someone does find scheme that allow them to beat gambling houses, then they will not share it with everyone, because if everyone uses this method (if there is one), they will quickly be excluded.
