I find this a strange criticism. If you look at all of human written stories, the number of stories is quite limited too. There's a lot of retelling of "classic" stories (except in classical times they were probably retelling them too). This even applies to religious stories:
The kings/men who fight over a beauty (which can be a land/crown, or a woman) overcoming a monster/evil opponent or a series of opponents (The Illiad/Troy, Beowulf, King Arthur, ...)
The orphan/abandoned kid/extremely poor that conquers the kingdom, either through marriage or by conquering a (series of) challenges (Moses, Aladdin, Oedipus, Theseus, Heracles, Cinderella, the foundation story of islam/mohamed, ...)
The vizier/prime minister who decides he'll be king and becomes incredibly evil to achieve it. (robin hood, paradise lost (ie. the story of lucifer/the devil), queen esther, aladdin, MacBeth, ...)
The not-evil-but-quite-evil mother who sees her king/husband make a child, either with another woman or sees/fears she or her child will be put aside because of the other child and ... (Hera, Snow White, Medea, biblical story of Abraham, ...)
And then there's stories like Game of Thrones that are in large part a combination and integration of a lot of such stories: Circe and her children. John Snow, after being rejected, climbing up and up and up. Bran becoming king. Arya living through a sort of Herculanean heroic epic. And the kings fighting constantly.
Humans are clearly still a big step up even from state-of-the-art AI, but we are not infinitely creative like we like to think we are. It's a difference in scale, not a fundamental difference.
