Depends on how your labels, or more generally the target data distribution, is generated. If it’s generated by human subjectivity yea I would agree. However it’s not hard to think of situations where the labels are the output of a physical process or, in the case of prediction, a future event. In these cases the label is not ambiguous and thus not subject to human interpretation. You also have RL systems that play games against each other and reach super human performance that way. Read about AlphaGo or AlphaStar for example.
