Isn't the difference between random chance and the complex realities of race and socioeconomic the entire point? I don't think a definition of racism as historically and culturally naive as to be blind selection bias that exists only in the current moment is worthy of any serious consideration - only useful as a straw man for arguments such as yours here. Any serious consideration of racism involves precisely the factors you mention. Education, nutrition, IQ, are all proxies for social class and I think you have to be quite biased to ignore how race relations throughout history have had direct impact on the current social status of race groups.
