False. The oldest DF carrier was Brook, and he ate it long before the Rumbar Pirates had died. In fact, according to the scene where they played Binks' Sake to their deaths, they apparently knew Brook's fruit would revive him, which implies it had been documented, which means somebody must have eaten it before. Unless Vegapunk has been working on Devil Fruits for more than a hundred years, there's no way he could have invented them.
