I think the answer is no real yes or no.
The sutta’s talk, for example, about things which are difficult to correct. One of those things, and i find this very recognisable, is mental distraction. Mindfulness of breathing is to be developed for abandoning mental distraction.
(AN6.115)
Mental distraction, i belief, comes with delusion. We become so easy involved in all these arising mental formations, like thoughts, plans, intentions, views. That proces of getting involved in those arising mental phenomena does something with mind. It is not easy to see this khandha with wisdom, ‘this i am not, this is not mine, not myself’. Most of the time, while these formations arise, there is an immediately grasping at those formations as ‘mine’. This is also called monkey mind. A monkey grasps a branch and then another. Mind does that too. There is constantly a grasping of this or that. We do not do this. It is a self-less proces. There is no self or I behind it.
Another sutta says one should develop mindfulness of breathing to cut of thoughts (AN9.1)
