It is a limited way of thinking of gambling. That IT is always only about money. We gamble when we drive a car that we won't get in an accident. We gamble when we get on a plane that it won't crash. We gamble when we eat food that we won't get ill. We gamble every day in every way all the time. You gamble on people 24/7
Some folks think in limited boxes.
Look up GAMBLE. While true it starts off by mentioning money if you read further you will find it has a far broader definition.
Definition 6. "ANY MATTER OR THING INVOLVING RISK OR HAZARDOUS UNCERTAINTY"
