Perhaps you were thinking of this?
“Yoda says, ‘When gone I am, the last of the Jedi will you be.’ ‘Of the Jedi’ could be a group of Jedi. You don’t know... That’s not to say I believe there are a lot of Jedi running around by Return of the Jedi. I think there are Force-wielding people, but whether they subscribe to the Jedi philosophy of how you use the Force is another question... But fans deal in absolutes, like Sith.”
He also points out a key line in the finale where Ahsoka says “I am no Jedi”—but still uses the Force and fights with two lightsabers.
“She does say ‘I am no Jedi,’ very clearly,” Filoni explained. “So if she says that and Yoda later says ‘When gone am I, the last of the Jedi will you be,’ he’s definitely not talking about her. There were so many options of lines to give in this episode, and one of them along the way of the season was that Ahsoka would mention that Yoda wouldn’t think of her as a Jedi because she’s not, necessarily, practicing that path any more. She’s still in the Light Side, for sure, but she’s not a Jedi practitioner per se.”
Whether or not that could cover the ultimate fates of Ezra and Kanan, Filoni would only hint.
