If you mean that pros don't care whether is called a "pro" camera? Of course they don't (are any actually called that?). Do pros choose their workhorse camera because it has a lot of features like those on my list? Absolutely. Otherwise they'd save money and get a Rebel. I'm sure the vast majority of pros that use Canon (for example) use a 1DX or 5D3 as their primary workhorse. Why? Because they have features not found on other Canons. Features that help them create images more easily and miss fewer shots. Could they make great images with other camera xyz? Sure, maybe, but it would probably be harder. In the absence of other constraints, they would use the 1D or 5D because it has features that make their job easier and the images better. That's why they own it. These features make it a "pro" camera, as in "the choice of professionals," "appealing to professionals," "designed for and targeted at professionals."
I shoot in a studio, using Profoto packs and Canon FF cameras (if Canon made a 56mm f/2.8 T&S I'd use a xxD camera) and a Foba Camera Stand (because I hate to hold griped cameras). I don't need weather sealing. I don't need high ISO, I don't need high frame rate. I use single-point auto focus or manual focus (depending on the lens used).
For location work I like the ergonomics of a xxD camera without a grip. No weather sealing needed because It Seldom Rains in southern California
I use light weight battery powered Profoto packs for location lighting.
