Quoted sentence does a lot of heavy lifting in your reasoning. Being intrinsically interested in something is integral part of learning. And, yes, obviously for people who have zero interest in subject it will act as "specific learning disability". I know this because I tend to be interested in programming-related subjects and, consecutively, capable of learning them, but I could never muster any interest trigonometry or calculus homework. I've also known multiple people who felt the same way about debugging their software development homework - they weren't interested and hated every second of it.
Saw plenty of this in school. Not appreciated.
I feel you missed the main point of my comment, though. Even if abstract reasoning, or certain forms of abstract reasoning, were not natural to you (something that I can impossibly judge), it wouldn't mean, as you initially claimed, that it would be impossible to teach you mathematics.
Just got a little upset about the rest. I wouldn't have reacted as I did had you phrased it a bit differently, like in the post I am currently replying to.
Either way I recommend reflecting on it.
