Exactly!

When an action is repeated many times, somehow, the brain decides to pass the task to the "automatic department".
The conscious portion of the brain is then liberated for more complicated operations requiring thinking.
After that point, that action is commanded with no mistake by the "automatic department", even when the conscious portion of the brain is not paying attention to it.

If you have to think about what you are doing, you are still using the conscious portion of your brain, with the potential for mistakes.

Repetition, repetition and repetition is the only known way of making the action to go in “auto mode”.
Driving a car and speaking a second language (tell me about it) are the perfect examples of this psychological phenomenon.

The bad part is that if you send the wrong action into the "automatic department", you will deal with repetitive mistakes in “auto mode”, which will be very difficult to unlearn.
I still repeat today some words that I learned to say improperly in English some years ago, regardless of how hard I try to correct myself.
