Agreed with your thought, it is impossible to win consistently in gambling and also impossible to win money consistently. However, the winning ratio can be increased by applying different experiences and strategies, but there are no guarantees. If there was a guarantee of winning in gambling then everyone could own a lot of money by gambling which is impossible in reality. I think a gambler is successful in gambling if he gets relatively high winnings, betting amount doesn't matter. Because the more money he keep in bet his amount of money automatically increased.
