Poor people come to gambling not just to spend it for nothing, but their purpose is to grow it. And even middle-class and rich people do. And all of them still gamble despite the losing experience because they wanted to win. I believe we just consider this totally for fun if we don't care about our money. 

We can't deny the fact that we are gambling obviously to make more money. We are considering this as an opportunity, but yes, a risky opportunity that can also ruin our lives if not controlled.
