If the fault is in the light and the ground probe is in the tank, then it is still through you.
On a side note a GFCI must trip at 0.006 Amps so I don't think 0.0059 Amps for a time of 0.0083 will be of any concern.
Plus the ground probe is a lower imperdance path to ground than any other possible path for the current, and lower impedance means higher current.
