Why do you play the lottery? To win the jackpot and be good with all your money problems. You never play lottery for the thrills because when you play it you know you'll lose 99.9999% of the time. It's not a fun game it's a dumb game to earn a lot.
Other games are completely different, when you play poker, cards, roulette or dice it's for the thrills. The winning streak, coming back after a huge loss...
When you play those games you don't aim to become rich, you aim winning and becoming slightly richer than before.
So you really can't compare lottery to any other gambling game in my opinion!
Well you have some point but there are people who plays gambling just for thrill or fun, that are the people who have too much money and doesn't know where to spend it anymore, that is why they are taking the risk in gambling, it doesn't matter if they lose or not just to have some pastime.
