USB Type-C rules are only for the physical connections — data speeds are covered by other rules. You can think of USB-C as a set of rules that only exist to make smarter USB plugs, cables, and connectors. Just because a cable says it's Type C doesn't mean that it works with every standard. It just means it plugs in with a Type C connector.
USB Power Delivery is a USB-certified standard designed to improve charging speeds and flexibility when charging devices, as power can be sent or received by a PD device. Unfortunately, power Delivery chargers can go up to or above 100 watts, which can cause serious damage if not used the right way. Still, PD's standards are designed to help prevent overheating and overcharging when using a wide array of devices with different power needs.
USB PD 2.0 and 3.0 are different than USB 2.0 or 3.1, and many cables will include both certifications since USB Power Delivery is part of the USB 3.1. Power Delivery can also extend beyond USB to other types of connectors, but since we're talking about USB-C cables here, let's not get too far down the rabbit hole.
If you plug a USB 2.0 cable into a USB PD 2.0 wall charger, the highest charge rate will only be 15W — the cable's maximum. 15W is a fast enough charge for charging a phone, but it won't be fast enough for many tablets, Chromebooks, and other laptops. If you want to buy a single C-to-C cable that can charge your laptop and your phone, buy yourself a USB 3.1 cable with PD charging; 2.0 is okay, 3.0 is better.
