"And black creators often did not get the same chance at success that their mainstream counterparts did, leading to some black creators filing lawsuits against YouTube. Despite YouTube's good intentions, systemic biases in how non-black users treated black creators, as well as the economic realities of Black people only representing 10% of the U.S. audience, have led to YouTube never doing quite enough to address this."
Is that because they are black though? Without asking those people why they watched something else you are just making the assumption it was to do with their skin colour and not anything to do with the content itself.
e.g. I don't watch a lot of content with women on Youtube. Not because I have anything against women. It because the subjects I am interested in, isn't covered typically by women.
Bluntly, yes. A lot of people in the U.S. are implicitly or explicitly racist. You can see this in statistics, such as 'black-sounding' resumes consistently getting less callbacks than 'white-sounding' resumes [1].
