Why are Asian men having so many descendants while non-Asian men - not so many?

My ex had the most common last name in the world - sharing with 107 million people.

You can tell these men have left some legacy in the world - making up a huge amount of the people.

Which means genetically they have been very successful.

Why are other last names so much less common, while some bloodlines are so successful?

Is it that Asian men are more fit?

I’d love you to prove me wrong, please.
