I see gambling as fun and not to earn money. If you take gambling as a source of income, I am afraid because that would definitely result to addiction which is very dangerous as the case may be. Gambling for fun is much okay for me because already it is advised that one should gamble with funds they could afford to lose and likewise gambling responsibly. With these, it in is pertinent that one needs be guided to know what to do if one must gamble.
While gambling to earn money, you make some loss, you would definitely one to recover your loss and in the cause of doing that, you would still found out that you are still making loses and that would trigger you to chase your losses which invariably means that you are prone to addiction. That is it when you decide to gamble for income but the other way round is not so.
If you gamble for fun, you will definitely have to set up a budget that does not affect your finance and with that, you can gamble responsibly as it does not gets you worried even if you record some loss.
