I used to be a CNBC junkie. Before there was crypto I used to enjoy adopting a penny stock and watching the ticker for it very closely; you can learn a lot about market dynamics when you are trading a stock where you buy $2000 of stock and that is 30% of the volume for the day. (Try $KBLB for a stock where if you think the price is too high or too low you will find that both opinions are vindicated if you wait long enough.)
Also those trades occurring "millions and millions" of times a day as opposed to a new pope every decade or so.
The comparison that I think matters is that the Pope and the Dalai Lama are the best-known religious leaders there are. I mean there used to be Billy Graham and the Ayatollah Khomeini but I think most people would struggle to name the leader of the Methodist church or Nichiren Buddhism or a rabbi of my than local importance.
Is that supposed to affect the comparison? A million trades seen by a thousand people each* isn't impressive, and numbers like that happen in all kinds of situations.
This is about the huge number of people knowing about a single event right away.
* I say a thousand here because even someone glued to every number on CNBC is parsing nowhere near millions of numbers. A much smaller sliver of people will see each of those individual trades.
