Eli5: How is it possible that advancement in USB allows us to transfer larger data in faster speed, yet the diameter of the wire does not change.

The diameter of the wire was never the limiting factor. Larger wires are only necessary when you’re trying to transmit larger electric currents, but large currents are not needed for faster data transmission. The data limit for USB is basically the speed with which the transmitting device can turn the signal current on and off again, and the ability of the receiving device to distinguish a signal changing at that speed.
