If football is Legal in most countries why is Gambling Prohibited

[Mauser]

Morally speaking some countries could feel the obligation to protect their citizens against the risk of gambling addictions. Even though only a very small percentage of gamblers actually become addicted it still presents a risk. Against this is the potential earnings for the government from taxes on gambling. I would argue that most countries allow gambling as it's a good tax income for the state. Then there are religious countries where gambling with money is not allowed. If the majority of a country following a religion that banned gambling it's nearly impossible for politicians to allow it. But even the strictest ban on gambling can't fully stop it. There will always be people trying get around it and create a blackmarket. For me football and betting belongs together, even if it's just a few bets among friends.

Technically soccer is a type of sport and it's not a gamble because the bets in soccer are different and not part of soccer.
Football is fundamentally different from gambling and this is something for sure.
As for why gambling is banned, in fact they are not really banned and only a few countries do have a ban.
that's because there are those that contradict the religion, norms and regulations of the government of a country itself.
