May I ask if the ancestors of Singaporeans also came from China?

Singapore is an independent country from Malaysia. Like Malaysia, there are three main races. But the largest population in Singapore is Chinese, a few Malays and Indians.

China people are China people who moved to Singapore before its independence. (That was before independence)

Malays are Malays, and Indians are just like China, but their ancestors are Indians.

(Speaking of ancestors, in fact, there are only two or three generations at most, and it didn't take long for the new horse to be independent).

So most ancestors of Singaporeans came from China. Because China has the largest population.
