You are purposely conflating two points - how does the leader gets selected (when we call someone alpha) and whether there is a leader. You are also assuming that alpha gets the most.

Further, how humans are organized changes massively across cultures and usually there is a shared leadership model - shaman and chief equivalents that tell us nothing about how wolves organize themselves.

Is it really hard to accept that there is another meaning that is in vogue, but you did not consider it instead of doubling down on a false assumption?
