So I just read that interview from last August from the CEO of Ubisoft. He is saying two entirely different things in it.
1. Piracy rate is 90-95%. He doesn't actually state whether he is saying played or sold. I would think it would be reasonable to assume he is talking about copies sold, which means for every 10 games sold, 9 are pirated.
2. Only 5% of players pay for the games. The problem is he is talking about f2p, and he's explaining that percentage compares to how may people pay for f2p, and then awkwardly saying they are about the same.
These two statements are contradictory. Honestly it's a bad interview, where the CEO is clearly stumbling over the numbers, and the journalist does nothing to correct or address the problems. Where is the follow up interview, by the way? This thing is posted all over, but this is the closest I can find to a follow up.

This is the closest thing I found, and they stick to the first statement, which makes more logical sense.
