Sure, but note that the numbers in this article only relate to the player market, not the directory market. Apple's marketshare in the directory market is noticeably larger because there is a good number of third-party players that use Apple's directory.
In the player market, there is also the fact that the Apple Podcasts player only exist on iOS while Spotify exists both on iOS and Android. While in raw revenue (or subscriber) numbers, with music the sum of iOS and Android certainly matters the most, looking how Spotify and Apple Music do on each of the two platforms is also a relevant metric.
