Those people who doesn't preferred to do gambling will not really understand those persons who still do gambling even the risks is obvious. No matter what statement you gave to them, it will be disregard.
I couldn't agree more, we can't really tell it depends on the person how he/she perceived gambling. Some may see gambling as entertainment because it helps them get away with stress or they find pleasure while gambling, others may look at it as wasting time and money. On the other note, a person who is happy with gambling will not think much about how much time and money was spent, what is important is that they had enjoyed doing it.
