In general corporate is commercial flying other than the airlines, except for instructing.
I disagree as well. Big difference between what you said. A wealthy person that owns their own jet doesn't necessarily mean that you'd refer to his pilots as "corporate pilots."
You also have charter pilots - who are more or less on-demand, "we need you guys to take us to a business meeting next week", type arrangements. They may work for a company (the charter business), but they dont have one sole customer they fly for.
Corporate pilots is used more to describe pilots who work for a specific company's flight department, and their sole purpose is to fly that company's executives, employees, and cargo to wherever it needs to go. They don't work for anyone but the corporation that signs their paychecks.
Everyone has their own general terms for different types of flying, but here is typically whats more accepted: Airlines, Corporate, Charter, Contract, Cargo, Agriculture, and Flight Instructors.
