I'm not sure.
a lot of the time is how things are taught/your motivation behind wanting to learn goes into it.
like, I've had things give me more difficulty than others that were close enough to compare, and it was largely because I knew what I was trying to learn (the thing I was having difficulty with) wouldn't be as important to me.
I've also had things "click" when my brother was explaining them to me when compared to other teachers because on some level, I couldn't let him have that over me, lol.
