The work per unit of charge required to move a charge from infinity to a specified point, measured in joules per coulomb or volts. The staticelectric field is the negative of the gradient of the electric potential.
Whereas electric potential differenece is the work done in moving a unit postive charge from one point to another.(its theoritically the difference in the potential ene
rgy of two point per unit charge.

Potential difference is the amount of work done by you to move an object in contrast to the force being applied to the object.
Imagine a case of magnets. We know that unlike poles attract and like poles repel.
When you bring two like poles near to each other slowly, you'll begin to feel some repulsion at a specific point.
Before that point, you'll not experience any force. That means, in 'no force' region the magnet won't go anywhere no matter how much you move it. That is zero potential. The first point, you kept the magnet had zero potential because the magnet remained at its place and the second point too had zero potential because there also the magnet didn't moved to go around.
Now, if we take the difference of the potential of two points, it'll be 0 - 0 = 0. That will be the potential difference, which is zero.
Now bring the magnet to the point where we started to feel little repulsion. Also, at that point magnet won't move because the repulsion felt is very very less (You can try that experimentally). Hence, the potential is zero.
Now, start to push magnet closer to other. You'll begin to feel some hard repulsion and have to push (or work) harder to make your magnet stay close to the other. You have to do work to keep it there. If you loosen your grip, it will fall back. That means, at that point, there is some potential greater than zero. Its value is positive. And if you subtract 0 from a positive, you'll get positive. Hence, the potential difference is positive.
If poles are unlike, the magnet will feel attraction and when you push it further to a point, it will meet the other magnet by itself. You didn't require to push it by yourself. So the work done by you is negative. Hence, the potential difference will be negative.
Electric potential difference is also something like this. But in this case, we'll take electric charges instead of magnets
Clearly, we can say that Electric potential difference is a sub-topic of potential difference. So there's no difference.
