Probability and Chance

Section 6 of Hume's Enquiry goes over chance and probability. Hume claims that the concept of chance does not even exist. It is our ignorance of the real cause of any event that has similar influence on the understanding. On the other side of the spectrum, he does claim that probability is existant. But I see the subject a little differently. There is chance in probability. If something is in fact probably, it has a chance of occuring. Therefore chance does in fact exist, but chance relies on probability. But then we can look at it from a different angle and say that they are almost the same thing. This is really really confusing so please comment on this!
