Do you really understand what you're saying, SM?

Jupiter is made mostly of unoxidised hydrogen gas, plus some helium and a trace of other stuff including the oxygen to make water.

There is less than 1% H2O on Jupiter so even if it did form an ocean it would be at the centre of a ball of gas weighing 300 Earth Masses and crushed to hellish pressures and temperatures by the load above.

In practice, most of the water is dispersed as water vapour in the body of the planet and any life would need to cope with intense up- and down-draughts, and huge oscillations in pressure and temperature.

In a word then,

NO.
