While minority technically means what you said, in practice people only care about those identifiable nonwhite groups who are doing poorly.
The result is that Academia is broadly in support of discriminating against certain identifiable minorities, despite their suffering well-known histories of discrimination. The logic is literally that the current success of Asians and Jews means that they are now in the oppressor class, and so should give up opportunities in the name of achieving equity. The same universities that used to discriminate against Asians and Jews out of simple racism, now wish to discriminate against Asians and Jews because they are trying to NOT be racist.
Many in my generation (I'm in my mid-50s) find this twist absurd beyond belief.
