Gamblers that prefer to love the process are more likely the ones who are away fron being addicted because they are probably doing it just for fun. On the other hand the one who are more focus on the outcome are the one who will probably become depress after loosing or worst become addicted because of wanting the jackpot
I'm more inclined to think it is the other way around
That is, it is those who are in for the fun of it that are more likely to get addicted. Those who are gambling solely for monetary gains will be disappointed by their results (if they are not extremely lucky) and leave as soon as they realize they won't be able to make any money with this activity. As other addictions prove (e.g. gaming addiction), you are addicted to a process (drugs, sex, rock'n'roll, to name but a few) rather than the end result, while gambling exclusively for money is certainly about the outcome (read, financial gain), not the process
