Thats simply now how dice rolls and percentages work friend, if you have a 10% chance of getting something is is statistically very unlikely to roll that dice thousands of times and still not get it, but it is still possible. That's where "lucky" and "unlucky" come in, adding a mythical quantifier to something that simply happens at random (yes technically rng generators are not usually TRULY random, but it basically is)

In other words, the smaller the sample size and the greater the tests the more likely you will eventually get the item. In your case, rng just caused you go happen to get 5 corvas more than the others. Another player could get 12 rivens and get ALL corvas rivens. Very, very unlikely, but still statistically possible unless DE has something in place that alters it slightly to prevent so many repeats.
