Podcasts aren't entirely learning, a lot of podcasts are pure entertainment, such as comedy podcasts.

Sure you can "learn" something from a Sports Podcast or a Comedy Podcast, but you could also say you are "learning" from a podcast which just reads out random numbers. You could "learn" at 33 minutes, 11 seconds, the number 6 is read out, then 8, then 1 but I wouldn't call that learning, or at least its pointless learning.
