A stock is ownership in a business, same as ownership in a house. It is an asset that you own.

When you bet on blackjack or the superbowl, you own nothing and are simply wagering on the outcome of an event.

Gambling and equity ownership are not the same.

There's more to stock trading than just "buy and hold". Not all investing has gambling motivations but it is absolutely used as gambling tool by many

You can gamble on literally anything. Stock prices is just one such vehicle.
