It's just the latter but the main is about making money with smaller amounts for not high risk takers but for those who made themselves a living with gambling, they consider it as a source.
I think that up to now only professional poker players like the ones we see on Pokerstars in Tv.All other people and gamblers play to win money but only to face with losses.That is what happens to most of us unfortunately but the truth is we all play with the purpose to make always more and more money.
A gambler will always aim to win and when we win, there's money = profit.
The aim was never to get entertained but to win money by which you can entertain yourself. I do not gamble for the sake of fulfilling my addiction I gamble when I feel I should try my luck to get some extra money which I can spend for my entertainment. Unfortunately it never always but sometimes it does.
