I completely agree with your assumption that these items shouldn't be used as the primary means of supporting a family or as a primary source of income. There's certainly some enjoyment involved, but as you said, these games can quickly impoverish someone if they have limited capital and aren't skilled.

Enjoyment, of course, varies and can come from various sources, but in this case, it should be personal, and only we can experience the rewards, whether we win or lose. In my opinion, fulfill your primary needs first, and then, if you're more likely to enjoy yourself responsibly.
