I have experienced something like this. My losses come when I expect more from gambling or when I need to win. I tried again and again but could never win there. But sometimes I have a record of big winnings when I gamble not to win but as a lottery without giving any importance. I have since believed that if I gamble more actively it causes me to lose more. But even though I know I can't gamble like that because I gamble sometimes because I need to win. If one gambles less then the amount of winnings will increase and if the winnings are not much then the amount of losses in gambling will definitely decrease.
