Drawing is a skill, not a talent. It is like typing: anyone can learn to type. Some will type 25 words per minute, some will type 60, and some whizkids will type 90 wpm. All of them are typing. Those who get the great speed and accuracy probably have some innate talent, or perhaps they work more at it because they enjoy it more. Maybe they enjoy it more because they work harder at it.
The skill of drawing is a mechanical ability to put on paper exactly what you see, or exactly what you mean to put on paper. It is not artistic at that point—it is mechanical, methodical, painstaking, and systematic. 
Once you know how to evaluate what you are seeing, break it down into its foundational parts, divide up the visual parts in a manageable way, and most importantly, see accurately, then the artistic parts come into play.
The only people who don’t learn are the ones who quit too soon. If you don’t enjoy the process, don’t truly want the product, and don’t push through the difficulties, then you won’t learn.
No blame, no judgement. Drawing isn’t for everyone, just as sports are not for me, and knitting, gardening, or baking bread may not be for you.
But you won’t know unless you try.

P.S All of today’s drawings are by my drawing students.
