Yes, it does.

That doesn't mean that the individual instances of gambling have nothing to do with chance -- its a product of the aggregation of the effects of chance. Given an infinite number of iterations of any random gambling scenario, you are eventually going to hit a losing streak sufficient to consume your entire bankroll (the size of the bankroll relative to the stake in any given iteration affects how many iterations it takes before you are more likely than not to have hit this point, but that's about it.)
But the existence of this effect (Gambler's Ruin) doesn't mean that the type of gambling has nothing to do with chance -- indeed, it only applies because gambling is about chance.
