And drawing well really depends on your standards, the time you devote to the pursuit, and your dedication.
If you are past retirement age and want to achieve the technical proficiency of a DaVinci or Durer while painting on the weekends, then I'm sorry to tell you, but that's probably just not going to happen.
If you are young and incredibly dedicated, and devote a lot of time to it, maybe you can achieve something like that (on a purely technical level, though it arguably takes much more than this to achieve anywhere near as much on an artistic level above sheer technical skill).
For those of us with lesser ambitions, a lot can be achieved without becoming very technically proficient. There's a lot of satisfaction that can be had from emotionally stirring, but perhaps not technically perfect work.
This is a much more realistic goal. But it's still a difficult one because you have to get beyond completely cliched depictions (unless that's what you're aiming at), and achieve some sort of technical proficiency. This will likely take some time and effort, but should be achievable for most people who can devote sufficient time and effort to the pursuit, and not give in to discouragement.
And then there are the so-called "naive" and "art-brut" sort of artists, who may have no technical proficiency at all and yet make work that is satisfying to themselves and/or others. There, by definition, they have no training to speak of, but often make art through obsession, mental illness, or for a wide variety of other reasons.
Finally, there are the so-called "weekend painters", who work infrequently, at their leisure, and usually without extravagant aims or demands on themselves. They can also be quite pleased with their output, and often create just for the sheer joy of it, or with a very modest aim of achieving a little technical proficiency. This is quite doable and quite satisfying for many.
Yes. Drawing is muscle memory/dexterity. Drawing/painting is a physically trainable skill.
Creativity however, is something innate (or at least a by-product of the nature/nurture of the person) and can be expressed compulsively regardless of the technical acumen of the pencil-wielder.
Creativity is certainly distinct from technical proficiency. However, much research has been done on creativity, and the consensus is that it can be taught and learned.
The compulsion or "drive" to create is something else, and perhaps that is more innate. I'm not sure what the research says about this, actually.
Certainly a lot of people "want" to be creative, just as they may "want" to write a novel. But few want to put in the hard work to make it (writing the novel) happen. Being "creative" is also hard work. Especially when you have to do it consistently and over a long period of time. Relatively few are compelled or driven to do so.
Yes? There are lot of books, videos and other materials that can teach you how to draw better. Like with coding, or anything, with practice you can become quite good at it.
