One study indicated that if a paint chip were to match a paint chip from a known sample (say a suspect’s car), there is only a 1 in 33,000 chance that the paint chip came from another random vehicle.

The statement above is TRUE.
The statement that is given above implies that, if a paint sample matches another known sample from a vehicle, that does not indicate that the paints come from the same source but it does show a very high probability that the paint samples come from the same object, if the compositions of the paint samples are the same.
