Do I learn 6000 kanjj readings in Wanikani?

So the question is if every new word introduced in Wanikani has a new reading or maybe some are repeating?

6000 on and kun readings sounds about right, but if you take a look at this article from kanshudo.com it says "There are 2136 Jōyō kanji, which in total have 3863 official readings" and I wonder where I can find those official readings listed officially and why they are official 🤔

Please don't write "learn words instead" 🙏

Thank you in advance!
