How many GPU's?

I'm trying to teach myself the basics of how a computer works. I was going down a path of videos called CPU Explained, GPU explained, etc.Though I got confused when i got to the graphics card. The graphics obviously works with a GPU but what's not clear to me is whether or not it has a seperate GPU reserved for the graphics card or if it uses the same GPU as the main RAM-related chip that works with the CPU aswell.

Thanks in advance for the help!

There are two main kinds of GPUs: integrated and discrete

An integrated GPU is just part of the CPU designed for graphics processing and must run at the same frequency as the CPU while also being subject to the CPU's strict size and thermal limits. This is fine for rendering a website or word processor or even simple 3D games.

However for tasks that require much higher amount of graphics processing a discrete GPU is used as part of a device we call a graphics card. The card has an extremely fast connection to the CPU and hold its own memory specialized for graphics as well as the discrete GPU itself. This GPU is generally physically larger, clocked to a lower frequency, and provided with a lot of cooling. The graphics card also includes a whole circuit board to manage everything of course but the GPU and VRAM and the brains of it.
