Ogg the Gamekeeper

Someone correct me if I'm wrong, but I think Hagrid said he got the 
Gamekeeper job after he was kicked out of Hogwarts (maybe right 
after, a year after - that sort of time frame)
Well, I though it a bit strange that Mrs. Weasley at the end of GoF 
was reminiscing about the gamekeeper that came before Hagrid (Ogg).
Wouldn't that mean she (and, of course, Arthur) were at school with 
Tom Riddle, Hagrid and Myrtle, or even *before* them?
