It isn’t. An equal size diesel and petrol engine will produce different horsepower, and the gasoline engine will make more of it. The difference is that a large diesel engine making the same amount of horsepower as a gas engine will make loads more torque and consume less fuel. This is why trucks and tractor trailers use large diesel engines.
Torque is useful because it allows towing extremely heavy loads.
TL:DR: Horsepower is how fast you hit the wall, torque is how far you push the wall.
