Mathematically, they are the same when it comes to calculations in equations.
Explanation:
EMF (electromotive force): is the voltage developed by an electrical source- maintains the potential difference.
Potential difference: observed difference in voltage between any two points in an open circuit.
Voltage: is both the quantity of potential difference and the unit of measurement, the volt.
For the quantity of potential difference, we use Italics V, which makes it clear which meaning is intended.
For this reason, potential difference is often referred to as 'voltage'.
