Simply incorrect, contradictions plentiful. Fisto, Kenobi, Yoda were masters on the council and Luke ended up as a master as well. Boba did wield a lightsaber in games and comics
I think you're being nitpicky. What I got from the first question is it was asking which characters were jedi knights at some point. Fisto, Kenobi, Yoda, and Luke all were and eventually got promoted. The other characters on there didn't make it to level of jedi knight. Also with the question asking which characters held a lightsaber, it didn't mention games or comics. I was only thinking of the movies or tv series.
But maybe it would be better to mention that only the movies count as source.
