If you are onto gambling for the first time it's not possible to get addicted to gambling because you haven't tasted what winning feels like, you will be consumed by doubts and uncertainty.
Of course there is no way addiction is come on a first trial but is come at the continues tense on the course of either winning or loosing.
But @ OP, a gambler can still win at a first time of gambling so does it mean at this moment one is licenced or triggered to addiction? Of course not. Addiction is a just habit.
Do you think its possible to become addicted to gambling when you haven't win a dime or after you win?
I think addiction starts after you win, even if it's just once, that's when you start gambling recklessly and you also start betting higher.
Not all winners or losers are responsible gamblers but all responsible gamblers are winners or losers.
Addiction is an edition that is activatedly inspired, enhance to advancement through the greed impressions of wins and can also be by the depression nature of loosing
