There are lots of Chinese and Indians, are you sure that there is a larger percentage who are good at math? When you take 1.4 billion x2 compared to 380 million Americans, the percentages don’t have to be high. Immigrants from those two countries at least, also tend to be in highly educated and more well off segments of those societies. You could find a lot of Chinese refugees from Vietnam in the early 80s not actually good at math, and instead having typical problems refugee communities have. You’ll also find this in African immigrant populations today if you compare refugees from east Africa to Africans who went the work visa route. Race isn’t really an indicator of anything compared to education background and the resources your family has access to (and inter generational knowledge on using those resources).
