You can find lots of discussions in terms of self-versus no self and what the Buddha really taught and what the Buddha really meant. I am staying away from going into an in-depth discussion of these various interpretations.
To share context, I speak to you as a Theravada Buddhist. And I draw on the teachings from the Pali Canon. I come from a place of working with teachings of these things are not self.
As in the answer to this question:
“And is it proper to regard what is inconstant, stressful, subject to change as: ‘This is mine. This is me. This is what I am?”
The answer is no, it is not proper to view that which is inconstant, stressful, and subject to change as self.
