I don't agree to that. people who are Interested about football or being active in football does not guarantee them being gamblers or bettors. I have encountered numerous people who only love everything about football but they choose not to bet just to avoid the risk of addiction on hearing the testimonys of others.
Yes, it is better to enjoy football as a sport than risk our money which can lead them to losing their money. Choosing to bet or not will be a personal decision and if they already know that betting can make them lose, they better stay away from betting.
No one can force them to be a bettor or gambler only because they know the most about the sport.
