It benefits Amazon to sell more head vs. tail items, easier warehouse and inventory planing. Amazon's "suggestions" and charts create a self-fulfilling optimization loop. Also factor in other variables like which publishers they have a better relationship with, etc.

Surely "most read" is based off Kindle statistics where warehouse and inventory planning don't really matter. And they're not in the "most sold" since, presumably, everyone already owns them who would consider reading them.

Also the Harry Potter books are part of the Prime lending library / Kindle Unlimited, so Prime members can read it for free without buying.

(Plus if I try to buy Kindle versions, I'm redirected - by Amazon! - to the 3rd party Pottermore website instead. Which, when I click on it, gives me an error at gbp.shop.pottermore.com that "The page you requested does not exist.")

I'd assume Goodreads which they own is factored into those statistics.

You are missing the point I think. Potter books aren't in the top 20 sold books, only the most read.
