If you are talking about God in the Bible, yes. If you are talking about gods in particular like Greek gods, no.
there were many kings of Gods people including Solomon and David, when you are talking about Gods people you are referring to the Jews, or Hebrews, if you are talking about the father of Gods people that would be Abraham.
That mortals are the playthings of the gods may be inferred from Oedipus' saying "What man more harassed by the vexing Gods..." in "Oedipus Rex" by Sophocles (495 B.C.E. - 405 B.C.E.).Specifically, the gods appear to like to set mortals up for failure and punishment. In fact, the play ends with the suggestion that it is only in death that mortals can be happy, in the sense of not having to look constantly over their shoulder at what the gods are doing and planning. Up until that point, mortals run an obstacle course that is determined, not by them, but by the cruel whims of the gods.
