Yes this shows that the models are, at least a part of the problem 13.91 million triangles is quite high. This means the first point on improving this scene should be the meshes, make sure that you reduce the tri count on your meshes. In most cases, you can get away with lower poly models, if you bake your high poly data (which already exists in your case) onto them (mostly normals).
That should be step into the right direction, and depending on your frame budget you might need to tweak further and or more aspects of the scene.
