Volts are the unit of the “pressure” (voltage) of electricity. Even if you don’t switch on a device, the battery provides it’s voltage. You need Volts first in order to do anything with electricity.
Applying Volts to a circuit then causes an electrical current to flow, it’s measured in Amperes.
Watts are the unit of power. Your phone charges with 5 Volts from USB, probably causing 2 Ampere to flow.
Volt x Ampere = Watt
5V x 2A = 10W
Your phone therefore charges with a power of 10 Watts.

If electricity is water, and that water is flowing through a pipe, then voltage is the width of the pipe and current (Amps) is the speed of the water flow (literally the current). Wattage, or power, is the overall volume of water (voltage multiplied by current).
So you could have a wide pipe (say 100V) with water flowing slowly (say 1A) through it, which would be 100W, or a much narrower pipe (12V) with water flowing so quickly through it (10A) that it actually provides more power overall (120W), all depending on the requirements of the device you’re powering.
