When you were a kid in school, you gamble in your exam when you didn't know the answer. Should I mark option A or B or C?
This isn't gambling. This is choosing when you have nothing to lose. If you don't choose any option you will lose anyway and chosing one at least gives you 33% chance to get it right. Gambling is when you have a choice not to gamble and walk away not losing anything and not winning anything. Not marking an answer in your test is losing and walking away is also losing.
Gambling should be for fun, not for getting rich.
People should be kind, courts should be fair, nobody should go hungry...
What's the point in stating the obvious?
