It's pretty difficult to find accurate up-to-date figures on who earns what in podcasting. For the most part, the information isn’t publically available. It’s only podcasters themselves who truly know how much money they’re bringing in. And they probably won’t be revealing that anytime soon! 

Rather than simply guessing who earns what, the best available approximation is Patreon. Not all podcasters use Patreon, but a lot do. So it's safe to assume that the podcasts with the most patrons are among the highest earners out there.
