Such stories are very inspiring! But as you know, these are isolated cases in a million.
And you seem to understand that it is almost impossible to win such a large amount with a small bet, but this 1% inspires and you think, maybe this time it will be me?
Almost impossible doesn't mean people can not win that such a large amount because I think some people can win that much money with luck. It is only a matter of time for that lucky person to win a large amount with a small bet, and maybe we don't know when that person can win those games. We might not hear that news because I think some people will not feel okay if their winning is published to the public.
