I wouldn't count on it. A real ground has a long copper rod driven in to
provide a low-resistance attachment to the earth. The concrete is a good
insulator, and unless the pole extends a considerable distance below the
concrete and is not corroded, the fixture is not grounded. At least not enough
to be considered a safety ground.
