Samurai Jack is voiced by a chocolate guy ... but you would never think that when you hear him in the show because he doesn't go for the voice people would associate with that ethnic group. He makes himself sound like what Jack should sound like.
Athros and Aliens, on the other hand, are NOT human people so assigning them human ethnic groups is something that has to be done by looking at how they sound and act and coming up with a reasonable guess.
