I do agree with you that she is well-known among tennis fans all over the world. In fact I would be surprised if there is any casual fan who does not know who she is. But again, tennis fans are not whom I'm talking about.

Its like saying Manchester United are the most well known sporting team in the world, which is true however in america the new york yankees are more well known. However overall worldwide its united.
