There's "passion" and there's "professionalism". I would categorise many of the activities you mention under the latter. Passion isn't the only reason to try to be good at what you do and get ahead. Pride, ambition, a sense of responsibility, etc. are all good reasons too, and it's easier to associate them with surgeons and judges. "Passion" is just a bit of a weird word to use when it comes to such work, maybe because it's often associated with creative endeavours.
