No, which is shown with Exar and Vodo. Vodo was a sixhundred year old jedi master, the best in the order, a masterfull swordsman and a staff which was better than lightsabers (so it said). Only months after ,Exar defeated him, some say even with ease. Months ago it was vice versa. Now they are different characters, but this clearly shows that just because someone defeated another through skill does not mean that they will do so later on, when the other has grown in power.....
And sorry, I misunderstood....
