How is such a small vehicle that connects to an airplane able to push it and direct it away from the terminal?

Airport tugs are generally quite heavy, have powerful engines and good grip. Tugs for large commercial aircraft often have additional ballast and weight tens of tonnes.
Aircraft are relatively light, even fully laden.
A point to consider: it generally only takes one person to push a car in neutral around, if slowly. What matters is sufficient grip and enough force to get it rolling.
Even then, compare the tug and aircraft to a rail locomotive in a freight train.
