Yeah, your definition is actually what matters.
If you are talking about appearance, there are all kinds of beautiful women out there, it's only impossible if you never show interest in them.
Of course, If you are not a charming, independent man, with your own life, place and car, you are not top quality material yourself in that regard and it's only logical to question why a very attractive woman would be with you.
However, remember that you are a unique human being. There are qualities no money can buy and good looks can't make up for which many of those "top tier" people are lacking. Women are actively looking for those also on totally average guys at first glance, so don't be afraid to try your luck with the hottest women out there if you think she would be a nice girlfriend, you might be just what she is looking for.
