Torque = how hard it can turn

Horsepower = how fast it can turn hard

They are closely related to each other which makes it difficult to separate them. Horsepower is torque times distance over time. Its power, which is work over time. Work is force times distance.

A slow rotation engine can be very high torque, but low horsepower because it can’t apply that torque over much distance. You can have a low torque motor that spins super fast putting out decent horsepower because it’s applying low torque over a large distance.
