No, they don't. If they go on to practice history of philosophy, sure, they become that, but many holders of philosophy degrees don't do that.

That's no more true than it is to say that what a person learns when taking a science degree is the eminent scientists of the past and their scientific results. Which is to say, that is a large and important part of what they learn, but hardly the whole thing, and there is utility in knowing what others have done in the space to doing new work in it. (Obviously, knowing the past of the field is also useful to people who wish to practice as a historian of the field, but its certainly not the only thing a degree is useful for. Holding a philosophy degree makes you neither a philosopher nor a historian of philosophy, both of those describe things you might do, with or without a degree, to which a degree might be useful.)
