You didn't really get the meaning of "woman is a woman"... It doesn't refer that there isn't diversity in style, thinking and anything else.
It was about that women have the natural need for love from someone, at least at one moment in they're life, just like the other half, it's part of the human nature. That means that boy "Y" has a slight chance to be the lucky guy to meet girl "X" (regardless of social imposed standards) and to make her smile for the rest of her life.
