I don't think it's true at all, but drawing definitely does help a little bit.
Or maybe it doesn't.
Who knows ? I've been spriting for six or seven years and it took me five before I even became semi-decent, and I started off drawing. Everyone's different, the only thing I can say is try it and see if it works out for you.
EDIT: It DEFINITELY helps to take drawing classes though, learn about perspective, anatomy, etc, and apply those in your sprites.
