There’s several of these even in the Yoda scene alone: Luke says he’s going to burn the tree down, then hesitates and seems to feel remorse about having wanted to. Then Yoda blows it up and laughs, confirming to Luke that, no, he was actually right in the first place to burn it down. Luke appears to accept this from Yoda, then becomes very defensive for a second about the Jedi texts. Yoda seems to tell Luke that the texts are better off gone, implying Rey already has what she needs without them. (JUST KIDDING; the Jedi texts are aboard the Falcon at the end in a shot I completely missed after seeing the film twice. What does this shot suggest about the Yoda scene, and Luke’s dialogue ABOUT Rey becoming a Jedi??? Does Luke KNOW she has the texts? Does Yoda?)
Yoda absolutely knows that Rey has the texts, it’s the whole reason he’s so cavalier about blowing up the tree. His actual line is “yes, yes, wisdom they held, but that library contained nothing that the girl Rey does not already possess”. He’s letting Luke think he means that Rey doesn’t need the books, but he’s actually saying she literally possesses them.
