Do you think both of these type of people have different mindset and one of them is willing to take more risk than than others ?
Also do think that gambling is for the entertainment and earning money too but people do betting only to earn money and there is no element of fun involved in it.
Most of the gamblers had already taken it to the next level where they seem not able to breathe well when any of those two are unavailable to them. Yeah! entertainment is not what they want, rather those profits will make them happy if they ever won. But as you can see, when they lose, there seems no happiness in their faces because they realize what they have done. They just lose it and thinking that will somehow find a way to get back what they've lost.
In both gambling and betting, the motive is to earn the money. There is no way that anyone is gambling and did not want to win in the end. Similarly why you bet on matches, because we want to win and earn money otherwise we can get enough entertainment by watching the sports of our choice.
