Horses use all four legs.
Horses only have four legs... so if you meant to ask "why do horses have four legs" then the answer would be that four legs fit the horses needs the most, for example six legs would make it hard to turn and would make the horse too long. But in the same way two legs wouldn't be enough because the horse would have to stand on its hind legs and since it wasn't made for two legs the horse wouldn't be able to stand up and would fall over.
The most major difference is that a horse's legs are not muscular like a human's. There is very little, if any, muscle mass on a horse's legs. Also, horses stand on their toes, unlike humans who stand on their feet from the heal (which is very similar to the hocks on a horse) to the toes.
