Have you ever experienced like you wanted to gamble but you can't do anything about it then you started to think what you can do for the meantime because you are bored or something like that? I have tried gambling with my friends when we are bored like if a red car passes by you would win, something like not on the ordinary or the norm in gambling but there's an exchange of value that's why it's still called gambling. If someone tries to prank someone, then they are willing to pay for it. It's the simple joys that you try to innovate.
What kind of gambling games/routines do you have? Have you invented a game where you and your friends start?
This is really common, many people make small bets with their friends with the difference that they do not exchange money or establish odds, however that is just the next step and when you do that then you can gamble on anything, for example you could gamble on which person is going to score the next goal in a soccer match, or who is going to catch the next pass in football, you could even bet in everyday things.
