You are right. Ambiguous means open to interpretation. But, ambiguity isn't a permanent state. After the final answer is given, what was ambiguous once, is no longer open to interpretation, since we know which interpretations was correct. Hence, by defination it is no longer ambiguous.

Yes, liking a reveal is about personal preference. The only thing I want out of the foreshadowing, is that they make the eventual reveal feel natural, and provide a new perspective towards the story. I think the show pulled it off pretty well.
