No, your chances of winning are greater if you buy more than one ticket (as long as they don't all have the same number). The probability of you winning when you buy two tickets is the probability of one ticket winning OR the other ticket winning. The probability of event A occurring OR event B occurring is the sum of the two individual probabilities, which is of course greater than either of the two individual probabilities.
