@Merilirem Perhaps I'm misunderstanding your post, but I believe that you and I are making similar arguments. "Most people with high mana have black hair" meant that there are people with a high amount of magic, and most of them have black hair(both Leonard and the girl clearly have a lot of magic, but only Leonard has black hair). With that said, I wasn't aware that black hair was exclusive to high magic, so I did originally assume that there might be people with black hair who don't have high magic. Also, I knew it wasn't 1:1, but to be clear I don't know the actual ratio, so in hindsight I shouldn't have used the phrase "most people" as it could very well be that few people with high magic actually have black hair. For all I know, it could be that 1 in 10 high magic users actually have black hair, which would invalidate some of my argument. Wouldn't be the first time I was wrong. ¯\_(ツ)_/¯
