How did the Parker Sun probe get to 500,000 kph?

This is vastly faster than any space vehicle I've heard of so how did this acceleration happen?

The probe orbits between the Sun and Venus. By using gravity to help accelerate it, the probe slingshots around Venus and the gravity from the sun adds momentum. The probe then goes around the sun back towards Venus.
