Many factors can affect tire wear. Driving habits, tire pressure, suspension design, overall load, road surface, and on and on.
The point of camber being the cause would assume that it’s based on suspension design. That may be the case, but as noted in comments, it’s just speculation without knowing the make/model/year. A sportier SUV may have factory cambered suspension, while one that’s more off-road oriented may have softer, longer-travel, suspension which is sagging more by design.
I think the most important thing to look at is that all 4 tires seem to be pretty even - that’s a good thing. If this were because of mechanical damage, it would likely be only 1 wheel, and very rarely more.
It can also just be cause by turning. Usually you’ll see the outside of a tire wear faster than the inside, but it’s not a stretch to think that it could be reversed. As I say, a sportier SUV may be cambered. It would also likely have tighter suspension. That would definitely cause inner-tire wear.
