Because most of them believe gambling is 50/50 and they only need to wait for their turn to win a huge amount of money.

They have a false logic for thinking like this, hence they can't stop to gamble, they don't see the reality if their chance to win is much way more lower than their expectation. I like their optimistic and how they really sure if they can win someday in the future, because to be a businessman require that mindset.

Someone who have been used to work with a company will think it's unrealistic a business which not making money can be profitable after 2 or 3 years.
