Everything you mentioned were only ambiguous before this reveal. Ambiguous means we haven't been given a clear answer yet. The reveal has given a very clear answer as to how Savitar found out about Reverb, Why he calls Barry the big bad, and why he is such a personal villain. The only thing about Savitar that is ambiguous right now, are his reasons for going evil and killing Iris.

Your points prove that the hints weren't too helpful in figuring out the mystery, but they don't prove the hints are still ambiguous even now.
