I understand what you're saying; I've seen a lot of movies like that where those who win gambling or get a jackpot suddenly change their behavior and their thoughts suddenly become different from the people around them.
Is it the type that suddenly doesn't know anyone, even those who used to be close to them who didn't do anything bad to them? They suddenly avoid you because they think about things that aren't true.
The gambler who win the jackpot or big winning in the gambling will do the share of the information to their friends.The jackpot money can be used by that gamblers for the welfare of their family members and their friends.The greedy will make loss of all the funds and make you loss the capital most of the time.Until the gambler loss the capital in the gambling site,he never worry about the game loss.Because the gambling capital loss will make you to reinvest the money to the gambling site to get back your own money loss in the gambling site.
It is better to use the money earn from gambling to take care of expenses than to lose it due to greed. There are scenarios whereby some folks have won a certain amount of money that can help them to start a proper business or take care of some expenses, but due to the mindset of wanting more, because is common among gamblers to always want to win more despite being lucky hitting the jackpot,a nf they will endup losing it all in the process of finding more wins.
Gambling can change ones lives for the better and same time ruins ones lives if not approach well , that's why we should be mindful with the way we approach it to avoid any painful or sad stories.
