Likely not: Arthritis would be inflammation of the joint, which has specific characteristics on MRI. Mild thinning of the cartilage is most likely just normal wear and tear for a 31 year old.

No, pretty normal: The thinning of the cartilage is not unusual. There is no tear which is good and ligaments are intact. There is no mention of bony changes which is the hallmark of osteoarthritis. Your knee should heal fine, consider physical therapy if pain persists.

Mild arthritis: By definition, mild thinning of the cartilage is mild osteoarthritis. Arthritis is the process of the cartilage in our joints wearing down with time. Since it is minimal, it is usually nothing to worry about.

Probably normal: "Mild thinning" is a very subjective and nonspecific observation, in the absence of other findings it is probably normal.
