Sportsbetting at least have a shot at using your knowledge and wisdom in some way. It is still a risk and that is why you are rewarded for taking that risk but considering all of other gambling games are purely luck based (aside from poker and some similar stuff) there is literally no game you use your knowledge as much as you use it on sportsbetting.
You need to know the teams you bet and you need to know the players and the pitch and many other details about the game you play and in the end you are more in luck than not.
