Yes. As long as its intention is for self improvement and not content you claim as your own. Any drawing you do whether it be tracing or from life, will help you grow as an artist. Tracing is useful when trying to better understand anatomy, perspective or the structure of any subject. That being said you still need to focus on rendering from observation. Even if you dont feel like the drawings look correct, you are working out a "muscle" in a sense. The more you do it the more you are strengthening that "muscle" and improving as an artist overall. It all depends on how advanced you are as an artist right now. If you are tracing for accuracy of your anatomy but you havent grasped the proportions or the underlying shapes then your are jumping ahead of yourself. But again, Yes, tracing will help you improve.
