Uncertainty of the insurance situation

Heyho, on the way home at night my car was damaged by the debris of a car that had just been crashed (I drove on the torn-off exhaust which was lying in the middle of the road —> Tires torn, rim over, lane adjusted ) … the accident car itself was not to be seen because on the one hand he was lying on the left in the ditch without light and on the other hand an ADAC truck (which I did not recognize as such in the darkness ) was standing right in front of me. tell me at the scene of the accident that my chances of getting the damage compensated are equal to zero. Since this was my first accident I am now quite at a loss and would like to listen to your opinion on chances and procedure Greetings Elarun
