Trust the experts. The well known teachers have enough students already and only pursue those they know to have talent. I remember my brother being pursued by many well known teachers (violin) and he studied in NYC, Israel and in our hometown. His main teacher was not well known, but could take him further than anyone else. There was a great chemistry btw. them.
I think what I'm trying to say is don't over analyze it yet. Now you know she has talent and she enjoys music. When it comes time to take more lessons, maybe even find a new teacher etc. take it one step at a time. This may be a great advantage she will have in the school application process that will set her apart from others.
