I think Rick's analogy of an actor was good, but not really done correctly. There are many actors that arn't Kevin Spacy. A lot of everyday actors that have small roles in all types of productions, but you will never seem them on IMDB or on stage winning an award and thanking the academy. But they are still actors and can call themselves that.
Regardless of how Emily plays, she not only plays on the women's professional tour and is currently ranked #20. Does that mean anything? Well, it means whatever she wants it to mean and she can call herself whatever she wants. If I play her in a tournament and win, I would say "I beat a pro*."
I don't know sh!t about tennish but I'm sure the women's pro tennis players (

The bar for women's professional is low, I understand that. Much different than the mens. Same could be said for the NBA and WNBA. But not only is someone who sits on the bench in the NBA (that would be the best player ever in the WNBA) is a pro, someone who sits on the bench in the WNBA (would might lose to me in a game of horse) is a pro.
I dont even care just giving you perspective.
