Human rater vs AI rater

I am really confused about my preparation.I took two speaking simulations.one from edusynch where human grader score responses and another from my speaking score in AI assist mode.
Edusynch 24/30
My speaking score 18/30
My speaking is heavily influenced by my first language.
But the question is,what can I expect in real toefl?does ETS gives the avevage of two scores?human and AI?
I am in peril!
