See....I think that the real sickness in gambling is believing in "luck." "Luck" is just something people say when they've won already....after the fact! If they win, they say, "I was lucky!' 
If they lose, they say, "I was unlucky!" 
But, that is something that can only be measured after the fact. If one relies on past probabilistic events to make future decisions, then they are already approaching the situation with unsound reasoning because the two events are unrelated. That's the sickness....believing in luck instead of relying on probability's chance and variation. Gambling is mathematical and not supernatural!
Well, actually your opinion is not wrong, but sometimes you need this luck to get you out of hard situation. I have experienced it few times, e.g. when I was playing poker, I did all in bravely although I held bad cards, but in the end I got full house. In sportsbook, sometimes I got surprising winning by bet on weak team against stronger team. Gambling surely is a mathematical, but don't underestimate this luck If they lose, they say, "I was unlucky!" But, that is something that can only be measured after the fact. If one relies on past probabilistic events to make future decisions, then they are already approaching the situation with unsound reasoning because the two events are unrelated.
