[How come do the buyer requests never match the metadata on my profile?]

I'm a new seller  voice over artist and I found somewhere that checking buyer requests regularly can help boost my sales. 

Now, to be specific as I've been in my profile, I'm a female North-American adult voice over artist. Why do I keep getting requests for middle age men or actors from other countries? Plus as a new seller I get to see a very limited number of options so seeing zero buyer requests that match any of my descriptions is quite discouraging. 

Is anyone else experiencing this?
