I work in healthcare in a specialist field, and the best are not the ones who get recognised. The ones who get recognised chase respect and fame - in healthcare that is going to conferences and speaking, and writing as many papers as possible.

But the best people in my field are the ones who do the actual job each day at an extremely high level. They go unrecognised except by those of us who understand what it takes to be good. They're humble and focused. Some of them for sure go and speak at conferences and publish papers etc but its not those things that make them the best, although those are the only those things that make them "visible" outside their place of work.

The same goes for music and actors. The most famous are not necessarily the best. They are the ones who people like or are the most commercial etc. The best singers are not necessairly world famous - they may be working professionally in less popular sectors such as opera or classical music or choirs, or they may be totally amateur. Similarly the best actors may be strutting a stage somewhere and never seen in a movie or tv show by the majority of the world. And even then they may be the "star".

Fame and notoriety has get little to do with talent - some famous people are undoubtedly near the top of their field but it is far from required.
