A camera's shutter speed is very different to the video frame rate.
A camera's aperture and shutter speed work together to control the exposure of a single frame. The aperture is like a small hole that lets light enter inside and get captured. The shutter speed (measured in seconds) is the length of time that the shutter remains open for each frame.
A high shutter speed means that the shutter is open for a smaller amount of time and hence less light can enter. To counteract the less light you would open up the aperture, or add more light sources. High shutter speeds are useful when recording fast-moving objects such as a game of sport, because otherwise the people would have lots of motion blur, especially if you freeze the frame (e.g. a tennis match, was the ball in?).
A low shutter speed means that the shutter is open for a longer time and hence more light can enter. So the picture will be brighter. But fast-moving objects will have motion blur. This is often used for artistic effect.
Frame rate, which you described, is the number of frames per second that will be captured. As you said, shooting at a higher frame rate (e.g. 60fps) and then playing it back at 30fps is a good way to achieve slow motion.
