I really don't understand some people's mindset of thinking they will win the jackpot if they always play gambling,
Can you win a jackpot if you don't play? I don't think so. You will only win when you at least make the effort to play, because then you give yourself the chance to win. You will have no chance of winning if you don't play at all, so I don't think people who have such mindset have an issue.
and even if the time comes when they win a large amount,
it turns out that over the long period they've been gambling, what they've won is still less than the amount they've lost over their time gambling in casinos.
This is not always true.
There are gamblers who have won life-changing sums from a
jackpot, more than the cumulative figures they have used in gambling their entire life.
This is why it is called a
jackpot, not a
huge win; there is a difference between the two.
