Macbook Pro port

In their specs at https://www.apple.com/macbook-pro-13/specs/

Apple calls them

Thunderbolt 3 (USB‑C) ports

The following may also help: https://www.imore.com/whats-difference-between-usb-c-and-thunderbolt

ThunderBolt-3 is an uncommitted computer port that can do almost anything, with the right cables/adapters. The first cable/adapter you attach specializes the port to one particular purpose, usually a more narrow subset of all it could potentially do.

USB Type-C™ is a specific feature of a product, it is not a generic description. Think of “USB Type-C” as an adjective not as a noun. 

Or think of USB-C as the name of the connector, ONLY.

In particular, there is no such thing as a USB-C cable. A cable with USB-C connectors at one or both ends could be almost anything. (example: the Mac charging cable plugs into that port, but supports ONLY charging or USB-2, and nothing more.) A different cable with the same connectors could be capable of daisy chasing a fast Hard Drive and a 4K display.
