Do PGA Pro's get to play private courses?

I heard that PGA Pros(the ones that work at ocal golf clubs and p that P.A.T. playing test) get to play almost any course they want to play regardless of memberships. Is this true? The reason I am asking because I desperatly want to play Winged Foot and Shinne Hills but I don't know any members of those golf courses. I am a single digit golfer close to becoming a scratch golfer and am wondering if I take the playing test to become a PGA pro, will I be able to play these courses and other ones that are private? Thanks for any advice.
