If I understand correctly, the job of the data cable is to transfer current from a wall charger or computer to a phone. Through this current the phone decipers the zero and 1s to make it code/data. Now shouldn’t current flow at the same rate between two cables, provided the thickness/resistance is the same?
​
Thank You!

There are multiple wires. There are data wires, and power wires.
The power wires deal with the charging, while the data wires handle data transfers. The jobs are not mixed between them.
The data wires carry a quite low amount of current, but they turn on and off very quickly. This switching of on and off is the data transfer. And in the case of usb-c, it happens much more quickly than lightning. Lightning is a standard that was made for significantly older hardware, so it tends to be slower.
