Yep, it can be subjective as people may view in different ways. We have the same opinion because we viewed most people around us spend their time for gambling or betting mostly to get entertainment than earning money. If their purpose is to earn money, they won't come to something that has a higher chance to lose your money than earning money. I am pretty sure that most people who gamble or betting know well about a small chance to win. That's why it is not a proper place to expect earning money. Moreover, if someone wants to earn regularly, he is in the wrong place.
