In gambling losses are inevitable, and that's why we should be contented with the little money you win and quit the game at the right time. If you are not contented, it means that you are gambling for profit and there is a big consequences that awaits those gamblers that feel gambling can give them profit.
Little wins can also be considered as the profit you get from gambling a bonus that comes with gambling as a form of entertainment, but greed is what usually makes anyone who wins little chase more winnings, thinking they can be able to use the luck they used in winning the first time to overshadow the casino, which usually lands them in losing even the little profit that was first made.
I agree that due to this greed people tend to lose more in gambling due to greed, people invest their saved money, even the money kept for their family in gambling they fall into financial crisis and their future becomes uncertain. Therefore it is very important to stay away from greed in gambling. There are some gamblers who bet more to get more after losing which leads them to further losses. One thing they should consider is that it is not possible to recover the losses in gambling.
