What is current?

The flow of electrons is current (by definition). But there is no flow of electrons without voltage potential (also known as charge).
So, when you have charged electrons, those electrons will flow, which is current.
The article at the website under Source(s) below may help you understand this a lot better.

The scientific name for the rate of flow of charge is current.
The potential difference between two points causes the electrons ( charges ) to flow.
The current is the number charges flowing per unit time.
It is suffice to say that there is a current in a wire.
Though it is not correct to say that a current flows in a wire, it is always understood as , " charges are flowing through the wire"

Because a currrent is defined as the flow of electrons. A voltage potential causes the electrons to flow and thereby creates a current.

Because that the definition of current, the flow of charge

Current flows only when there's a potential difference. when e's flow, a potential difference is generated and thus, current is said to be flowing.current is flow of electrons from a higher to lower potential.
