Super confused about this! Any explanation would be greatly appreciated.

Each wheel have an ABS sensor that measures the speed of the wheel. When one wheel suddenly slows down and not the others it reduces the pressure in the brake line for that wheel to avoid it locking up.
Traction control is indeed a further development from ABS. When ABS first came out it was made as more of a bolt on solution to existing car designs. So it would be a simple separate unit which only solved brake locking. That makes it a very important safety device. In order to do anti-skid you need more sensors for the throttle position and steering wheel. The ABS pump also needed to be double action, not only releasing pressure but also applying pressure. So this became a more advanced and more integrated system. It is also not considered a safety device as it is mostly used to allow for higher speed over slippery surfaces. The crashes it can prevent are quite rare compared to the crashes that ABS is preventing.
