We are merely .05% of the world population (if that). Our achievements in proportion to our numbers are staggering. Has that nothing to do with yichus? And no, not “everyone” is special(hence the hatred of the nations throughout history)
We are talking about shidduchim here. Since you would never consider a non-Jew for a shidduch anyway, it doesn’t matter how small we are compared to the rest of the world. For the purposes of shidduchim, the “universe” consists only of Jews and, in that regard (converts excluded), we are *all* descended from Avraham, Yitzchok and Ya’akov… so, for the purposes of shidduchim, it’s nothing special — since everyone has those attributes.
