How do extension cables or power strips supply power for 3 plugs if they’re only plugged into 1 outlet?

What is electricity? Two disconnected conductive pieces of material with a different number of wandering electrons have a “charge” between them. The moment you connect them, the electrons will flow from the one with surplus to the one with deficit.
By letting the electrons march through the filament of a lightbulb, or the windings of an electric motor, you make them do work on their way.
Electrons will march on any bridge between the conductors, no matter the size, shape or number. If you connect 5 lightbulbs all will light up. A power strips is just a convenient way to extend the range of the conductors and branch them for easier access.
