Is it easier for Koreans to apply for Korean nationality than other nationalities?

I am a Korean, and not every Korean can apply for Korean nationality at will. Only parents and children with Korean nationality can apply for nationality. If the family has stateless parents, then nationality is unacceptable.

Therefore, among the 56 ethnic groups in China, only Korean people have Korean ancestry. This can prove that it is easier for Koreans to apply for Korean nationality in Korea than other 55 ethnic groups. There are currently 500,000 Koreans in Korea. You can see that, right?

Do parents of other nationalities have nationality? Do you have any ancestors of Korean descent? Of course not, so it is more difficult for other nationalities to apply for nationality than to ascend to heaven unless they get married.
