Betting means two people, things or in teams (groups) are competing against each other and people are betting on it. That is not gambling.

Gambling is when you are gambling on games like the casino games. You are no betting that this or that person, thing or in teams will be the winner. No competition in gambling.

That is the reason on gambling sites that sport betting are in different section other than casinos because they are different from casino games.

All these things have differences. But people will not argue because many gambling sites are also betting sites. But trading is entirely different. If anyone says they are both the same with trading, we agree about their risks bit disagree about theit design.
