Current is indeed the flow of electrons/charges.
 
Whenever there is current passing through a conductor there are usually trillions and trillions of electrons flowing together through a small area of the conductor.
 
A small current like 0.1 μA will have 6.25 × 1011 electrons flowing through the conductor in one second.
 
These electrons together form a large enough current which enables daily appliances and even motor, to work.
