Yes urgent care is outpatient care since you won't be admitted to the urgent care center and if you do need to be admitted to a hospital the urgent care will either recommend a hospital or send you there by ambulance if needed.
Urgent Care is a good option when you do need immediate medical care but the medical care you need doesn't warrant an emergency room visit.
The urgent care center will be a much cheaper option than going to the emergency room and you usually get seen faster in the urgent care center than in a more busy emergency room.
