I should hope so, that's kinda what you do when drawing.

Also you'd be surprised at how much tracing over real people helps. And it's not as though it's a beginner's technique, professional digital artists do it all the time. It saves time and effort and gives amazing results. Besides, if you only trace the skeleton then the only thing that you get from tracing the image is proportions- which helps you learn human anatomy better.

There is literally no disadvantage to doing this because everything else about the image (the texture, colour, lighting, outline, details, etc) are all done by yourself without tracing them.
