I remember years back before I knew about sport betting; there was a football viewing center close to our house. The noise and jubilation that comes out from there always makes us wonder why people love football so much. Not until I realized the shout and jubilation was because people placed bet on those matches.
So, it's not like they are happy their favorite club won but because they won.

Do you get excited because your favorite club won or because your ticket won?
I am a fan but once I bet on the game, I am neutral. My bet is more important than my fandom in this instance.
If I get excited, it is because of my winning ticket and not my club. That is what I always look out for and is most important to me. Gambling has made it to be that we monetize our passion and the passion is for the game and not the club.
Winning means that I am getting more money and I am betting the house edge. The passion for the game keeps me going not my favourite team that is possible to change at any time.
