In my opinion, the first sign of gambling addiction is that the person regrets the lost money but again and again visits the gaming platform in the hope that today he is lucky and winnings will contribute to changing his life for the better. He comes to the casino not to enjoy the game, but for the result, which often turns out to be not what he expects.
The manifestation of stress, depression, gambling with credit money, etc. is already a neglected degree of gambling addiction which is very difficult to cope with alone.
Actually this is quite natural if indeed their goal is to depend on their finances in gambling so that indeed this has more and more urges so that when trying to stop this it is as if they have nothing else to do so Gambling is the solution.
When this happens then gambling is actually something that is very difficult to get rid of and addiction will not be prevented.
