No. But Rex's real fate hasn't been confirmed yet
First of all, Ahsoka and Rex's fates have not been revealed yet. So we do not know what happens to them yet. And since you said Naboo, you might be referring to the episode with that blue virus. No. Ahsoka and Rex were given an antidote that saved them from the fatal virus. Another clone and Padme were also saved.
