Do you know that for certain or are you speculating?
Sorry, but I do not subscribe to this interpretation of no-self.
The Buddha reprimanded a monk who held that interpretation
“So it seems, good sir, that form, feeling, perception, choices, and consciousness are not-self. Then what self will the deeds done by not-self affect?”
Then the Buddha, knowing what that monk was thinking, addressed the mendicants:
“It’s possible that some foolish person here—unknowing and ignorant, their mind dominated by craving—thinks they can overstep the teacher’s instructions. They think: ‘So it seems, good sir, that form, feeling, perception, choices, and consciousness are not-self. Then what self will the deeds done by not-self affect?’ Now, mendicants, you have been educated by me in questioning with regards to all these things in all such cases.
The Buddha didn’t reject the existence of a being:
“‘A being,’ lord. ‘A being,’ it’s said. To what extent is one said to be ‘a being’?”
"Any desire, passion, delight, or craving for form, Radha: when one is caught up there, tied up there, one is said to be ‘a being.’[[3]]
"Any desire, passion, delight, or craving for feeling… perception… fabrications…
"Any desire, passion, delight, or craving for consciousness, Radha: when one is caught up there, tied up there, one is said to be ‘a being.’
The aggregates exist
“Form that’s constant, permanent, eternal, not subject to change is agreed upon by the wise as not existing in the world, and I too say, ‘It doesn’t exist.’
…
“Form that’s inconstant, stressful, subject to change is agreed upon by the wise as existing in the world, and I too say, ‘It exists.’
The Buddha used pronouns constantly, and that does not mean he wasn’t enlightened, so the language one uses is irrelevant.
No-self doesn’t mean no control either, as the Buddha had mastery of control.
"And, yes, I think whatever thought I want to think, and don’t think any thought I don’t want to think. I will any resolve I want to will, and don’t will any resolve I don’t want to will. I have attained mastery of the mind with regard to the pathways of thought.
No-self has to fall in the context of suffering and conditioned things. Suffering is no self because you don’t choose to suffer, you only suffer because you don’t know better. If you could choose not to suffer, you would. Once you know better, you’re no longer ignorant, you no longer suffer. All conditioned things are no-self because they’re all impermanent, if you knew better, you wouldn’t settle for conditioned things.
Whether a being exists or doesn’t exist in parnibbana is one of the topics the Buddha said should not be discussed. The unanswerable questions - Wikipedia
Again, because it’s speculation that cannot be known until you do know it for yourself directly.
