It can be both of them however in 99% of the cases it will be the biggest nightmare of our life.I say so because only 1% of the gamblers are able to hit that jackpot that is a life changing event and all the others keep chasing it without any success.However it is exactly this that keep gamblers coming back and that is what keep us going,we think that today will be finally that lucky day for us when we will hit that big win,the big win never seems coming so we continuously run like a loop in a switched network and there is no remedy but going to addiction.I hope though that every one of us hit that big win,yesterday I lost a lot of money chasing it without success,now I try again next week.
It is totally useless to chase the jackpot no matter how much money you have. Gambling is all about luck, and if you are not lucky, you won't get a big win even if you spend a million dollars, and if you are lucky, you might get it on your first bet that you make, that happens to some people but as you said, it isn't the case with about 99% gamblers because the house always has an upper hand.
Winning a jackpot is too rare of an event to be witnessed every day, if I am honest, I've personally never seen anyone winning a life-changing amount of money in front of my eyes in my entire life, I've heard stories about it but I've never seen it happen, that is how rare it is.
