You can easily tell a person who is addicted to gambling, yes they are chasing their loss, it's one of the obvious signs they are always excited to get back on the table or log in to their account and promised themselves that they will regain their losses, they take out a loan and try to convince people that they can win this time, but that this time will just go on and on.

Another sign is they are showing sign of excitement they don't care if they win or lose they just want to play they just want to be on the board they forget every issues and personal problems, these kind of gamblers don't have a strong support system and they find gambling as their scapegoat.
