If your company takes a pile of CVs and randomly picks a bunch of people to hire, then yes, you are absolutely correct, there is something very very wrong with company B if a truly random process results in an unequal distribution of hires.

But hiring isn't random. Maybe all the "brown" candidates lacked necessary qualifications. Or needed visas which they couldn't get. Or a million other reasons other than "org B is racist".

My point is: you need further context. To look at that one stat as given above and conclude org B is racist is....unwise.
