Being an A or B player isn't something that happens at birth. Your performance at work depends on a lot of factors.
But there are B players out there, and A players are doing better work than them. This is irrefutable if you've ever worked on a team of significant size. It's not supposed to be some personality-damning attribute that implies a B player is forever doomed, or always brings less utility to the table than an A player. It is specific to their current role, work, etc.
