Nobody has ever just suddenly become good at something with 0 practice. Usually, there's a strong correlation between time spent on something and expertise.
If the discussion is about quality vs. quantity, then this is a strawman. You can make a 100 shallow todo list apps, and they'll all be worse than one you focus on and polish over time. That story about the art class is most likely not true and most likely not applicable to other examples. But maybe part of that polish is experimenting with smaller prototypes.
The point is to always use advice like this as a principle and not a singular source of truth.
