Space is filled with junk

Space junk is real but just need armor and redundancy and put satellites in similar direction as space junk (lower relative velocity). On the relatively 2D surface of earth, what is the chance that if I randomly drop myself onto a random spot on the planet that I'll land on one of the billions of cars? Orbit is 3D so the amount of locations is some insane number so there's more space up there than we can ever fill. I might be wrong tho. My intuition is not based on science, just my thought process.
