This isnt mathematics, no one can give you an accurate answer.
At best i can tell you its not looking well.
You are an old graduate and your scores are not so hot.
If you can:
get valid US experience at as University hospital and score some good letters, do research and publish in important journals.. this all takes time so i dont think youll be able to do it.
The best thing you can do is apply SMARTLY. Apply to 100+ programs, specially community and maybe a couple of low end universities (like 10 at the most).
This is assuming you are interested in IM/FM/Peds
