It's not like I ever gotgud at drawing, so take this with a grain of salt, but here are some scattered observations...
The way to improve is to practice drawing different things. Investing the time and doing a variety of things so that you're always challenging yourself. You might call this "practicing broadly."
Practice sessions should probably include a little drilling of basic strokes. Or at least, I found that to be helpful; my lines became straighter, circles more circular, etc. You might call this "practicing deeply" because it focuses on mastery rather than learning.
Practicing along both dimensions entails a large investment of time, but it seems to me there's no better road to be taken.
Even professionals might undo and repeat a lot of their strokes as many times as it takes to get them exactly right. (I discovered this watching Artgerm streams.)
A saying from martial arts: "Practice makes permanent; only perfect practice makes perfect."
A novice get the wrong impression that "I have no talent for this" because their strokes always come out wrong, but the problem is actually simple: they need to move their arm more instead of relying on their wrist/fingers. Make sure you're set up with good ergonomics, and do some research about basic drawing technique if you're not confident about yours.
