If you want the best possible answer to your question, read "The Sports Gene" by David Epstein. If you have any background in biology and basic genetics, you'll walk away so much more knowledgable for having read it. It will go into detail about things like trainability that can only be scratched at surface level here.
So, let's scratch that surface. Kenenisa Belike has a genetic ceiling. I have a genetic ceiling. The difference is that his genetic ceiling is a sub-27 10k and mine is a sub 38. He was born with a higher VO2 max, better running economy, more durable muscles, better muscle-tendon elasticity, a more efficient frame, etc. He also, by virtue of being elite, likely has much better trainability--that is, his body improves more after a given day, week, or month of training than mine does. He is also more determined... I truthfully could not handle the 100-mile weeks ad infinitum that he can. The same would likely be true of you and an elite female runner. I cannot speak for your determination, but all the other factors are likely true.
Scale down this principle. The same is true of me (and likely you) and all D1 athletes and high school state champions. Their genetic ceiling is much higher than mine.
If you accept that running is getting the most of your potential, you can certainly be successful. If your goal is to be a world record holder, my advice is to give up.
In all seriousness though, my advice is to, in the advice of many message boarders here, "Just run, baby." There is no other way to find out what your ceiling is. And there is perhaps no bigger joy than thinking you know what your ceiling was--and breaking it. I'll never run a sub-60 half, but I remember the day I ran 1:24 in the half as an incredibly proud moment-- it was better than I ever really thought I would be. You have moments like that out there... as long as you keep after it.
