The AmStaff itself is a distinct, kennel club recognised breed with a written standard and organised health testing, including screening for its known conditions. Pit bull is a broader informal term that often sweeps AmStaffs and similar types into one bucket, which is exactly why laws and headlines confuse them.
In the right home the AmStaff is a joyful, loyal clown with a heart as big as its head. The AmStaff suits committed, active households that want a devoted, athletic companion and will do the socialisation work properly. Owners should also check local rules, since breed specific legislation affects this family of dogs in some places.

If this question is part of choosing the breed, run it against your worst week rather than your best: the exercise in the rain, the grooming in a busy month, the dog care during a family illness.
The standard range is 17 to 19 inches at the shoulder and 40 to 70 lb, with a typical adult near 55 lb. The growth table on the American Staffordshire Terrier profile shows the expected weight at each age on the way there. The record's numbers, 5/5 energy and 3/5 trainability among them, are averages from real dogs, and meeting several adults shows the spread around them.
Energy at 5/5 predicts it: high scorers patrol and participate, low scorers supervise from a cushion. Around the house the American Staffordshire Terrier also needs its 45 to 90 outdoor minutes regardless of indoor tempo. Meeting adult dogs of the breed remains the best final check on any written answer, this one included.
It depends on the dog's prey drive and upbringing more than on the breed label. The American Staffordshire Terrier's record with dogs reads With early socialization; cats it is raised with are usually accepted, while strange small animals outdoors are a different question for most dogs.
