Yes, the flow of electrons in both galvanic and electrolytic cells is the same: anode -> cathode

From the salt bridge?
Just think about what is happening.
The anode is having oxidation occur which puts more cations in solution - so anions from the salt bridge will move there to balance the charge.
The opposite happens in the cathode.

The anode and cathode are defined by the reaction occurring at them.
If you have a galvanic cell, you can pick out which electrode is the anode or cathode. If you were to then apply a sufficient voltage to turn the same cell into an electrolytic cell, the anode and cathode would swap from when it was functioning as a galvanic cell.
In these cases the salt bridge ions will move to balance charge as previously described.

So is this correct?
In galvanic cell, anions flow to anode and cations flow to cathode to balance charges.
In electrolytic cell, anions ALSO flow to anode and cations flow to cathode to balance charges.
