Change of state with 了
Sentence + 了
了 at the END of a sentence signals a new situation — something is different now: 下雨了 "it's raining (it wasn't before)", 他二十岁了 "he's twenty now".
This is a different job from 了 right after a verb (completed action). Sentence-final 了 is about NOW vs. before. A very useful case: 不 + verb + 了 means "not anymore": 我不喝咖啡了 "I don't drink coffee anymore".
