And not to sound racist, but black people have (often) very different stench from the rest, that one is not Chinese (racist) myth.
But to be honest every race/nation I met stink, your nose is just blind to the people you meet most often. It's same with my apartment when I return back after longer vacation I can notice its specific (new) smell still even after years living there (especially if I won't leave windows a bit open for air exchange), but if I'm away just for a day or two I don't smell anything.
As one who's hung out with bohemian vagabonds who didn't make a routine habit of bathing, my nose has told me otherwise.
Nice people but... humans smell funny in general.
A fact of life that seems pointless to try to avoid.
One person's BO is another person's aphrodisiac. Biochemistry is fun, lean into it!
