I think it is definitely Trelawney’s prophecy! If you study carefully, you will find that every time Trelawny's prophecies are correct! ! Let me tell you how to evaluate Professor Sybill Trelawney in "Harry Potter"!

"Around Easter, one of us will leave everyone forever." - Result of the first divination class: Hermione left Professor Trelawney forever around Easter classroom. "The thing you fear most will happen on Friday, October 16th." - Result of the first divination class: Lavender's biggest fear was to hear the news that her rabbit died, which later came true. .

"After you broke the first teacup..." ——The first divination lesson Result: Neville broke the teacup! "When thirteen people eat together, the first one to stand up will be the first to die." - The Christmas Dinner in Part 3 Result: This prophecy spans a long time and was not fulfilled until three years later. In fact, before Trelawney arrived, the dinner table was already filled with thirteen people. Because Ron's mouse "Scabbers", also known as Peter Pettigrew, was in Ron's body at that time. Counting Peter, there were exactly thirteen people. Among the thirteen people, Dumbledore was the first to stand up. Dumbledore stood to greet Trelawney. It turns out that of the thirteen, Dumbledore was the first to die.

"You will be late for the next class." Whether this prediction is accurate or not seems not to be mentioned in the novel. But with Neville's memory, being late should be a common occurrence. This seems to be Trelawney's most inaccurate prediction. But what if she was predicting the Defense Against the Dark Arts teacher who changes every year! Or it refers to the students who died in the Battle of Hogwarts! Of course, we can also think that this is indeed her way of joking with the students deliberately.

The book "Harry Potter" has already surpassed the category of excellent!
