Whoever thinks gambling even gives them hope like lauder_larger stated is only living in a huge fantasy. Every gambler gives them-selves hope based on luck with an outcome that is usually negative anyway. It is more like 1 person out of 99 winning while the others losing and the 100 of you trying to fight for that winning spot.
They are all fighting to win that spot mate. No one will win and the casino will milk out money from them. The addicted gamblers dont realize that and so if someone who is responsible with their money and knows where to spend it would not gamble it. Everything has a limit and crossing that limit will only lead to bad conditions. Its the same with gambling.
Seriously, where is the hope in this and where is the fun as well. If I want to have fun, I would rather watch movies or play video games.
For some people the thrill of winning big and winning jackpots is what drives them. But I would say it leaves them hanging high and dry before they even know it.
