My final stats , also have one doubt

So I beat erlang , so I have unlocked the true ending right? . I still haven't even met wukong( final) . Some say u need to beat wukong 2 times to get good ending or something? .

This is my 1st playthrough , just defeated erlang I'm afraid now I have locked myself out of the true ending , is it true?

Also erlang fight was so cool.
