It doesn't matter what are the odds : if someone is writing the story, then this someone will do whanever he wants. The writers are gods in this universe. If the writers (and George RR Martin) want the Night King dead, then he will die, no matter how powerful he is.

So, we know that his fate depends on the writers. Personally, I can't imagine that we would have 8 seasons and 7 books only to see every character dies for nothing. What would be the point anyway ? Nearly no one wants to see that happen.
