Yes, being part of the team is one achievement, being leader of the team is another achievement on top of that.
Sorry there's not "participation prizes" for everybody, but there are concrete important differences between being team member and team leader, as much as some seem to want to delude themselves otherwise and give themselves the "consolation prize" of feeling good, instead of getting the result (being the PI/project lead and getting the Nobel) they wanted.
Zero sympathy for the people who would want to Nobel, now trying to diminish the achievements of those who won the Nobel, just to console themselves. Everyone knows how science works. There are teams and PIs and projects and project leaders. Instead of crying that the reality is "unfair" if the complainers actually cared enough about winning, they would have tried to position their careers in such a way that they were competitive. To pretend you were disserviced when you know how it works is disempowering your own potential to have done better, and also really disrespectful to diminish the importance of Nobel recognition, to people who contribute to winning those prizes.
TL;DR - Looking at the group complaining about not being recognized, all I see is a bunch of sore losers, inventing disempowering reasons to console themselves, instead of inventing results for themselves. Take personal responsibility, be inspired by the achievements of others, these traits will help you win.
