The quality of a king thing is so incredibly vague that you could find a way to say everyone has the qualities of a king. I could probably find a couple panels that make Chopper look like a CoC user but I'm 99% sure he doesn't have it
I think CoC is completely random. If Oda wants to give it to someone he will and if he doesn't want to he won't
Chinjao had his will broken by Garp and didn't even attempt to do anything for the rest of his career but he has CoC and Law (who risked his life trying to overthrow 2 Yonko) doesn't yet
It makes no sense to me but that's how Oda is writing the story
