No.
When a wheel loses grip and stops rotating under braking, the ABS modulator interrupts the supply of brake fluid to that wheel. As soon as rotation and therefore grip is achieved, the modulator restores normal manual brake function. Usually this cycle repeats very rapidly resulting in the vibration felt at the pedal as the pressure is released and restored at high frequency.

Yes, that's correct. ABS will stop the car sliding and maintain effective steering but it cannot shorten the stopping distance.

There are four sensors as Popcorn has explained.
