A recognised illness
The World Health Organization recognises gambling addiction as an illness. It is neither a lack of willpower nor a character flaw: it can be treated, with the help of professionals. Sports betting is concerned in the same way as other forms of gambling.
What it is not
It is not limited to those who “gamble a lot”. It is not a matter of intelligence or of knowledge of the sport: a real tennis expert can be affected.
What it is
A gradual loss of control over gambling, which ends up affecting daily life: finances, mood, family, work.
