I had never heard of her before and still do not know who she is. All the same the example worked well for me. Whether I had heard of this person or not seems of little importance.
The point he was making was that talent by itself is insufficient. While presenting her as a case study he gave enough information to convince me that this person clearly was someone with a lot of physical talent. Specifically he mentioned that she was an olympic gymnast and moreover that she wasn't only excellent but one that would routinely get full marks. All the same she was not good at skiing because she lacked knowledge of skiing and practice (in his words the main factors contributors to quality).
