I wouldn't say that, per se 
I'm a digital artist who made that transition from a traditional artist, and a lot of the things and methods I did with the latter really helped my skills in the former.
It's good to consider what s.j.meek has mentioned. Sometimes, the best way to improve and learn a new media is to take in the skills you've gained from another one. For me, traditional art really helped me steady my hand to give neater lines, especially when inking with Inking Pens. As a result, I can easily do quick, neat lines with a flick of my wrist.
