Depends on the rest of the information that follows the expression, the persons individual emotions at that time of using that expression as well as the internal representation that the individual creates.
There are times when I can't does become I can. However emotions and internal representations speak louder than the spoken words we utter about ourselves.
When we say I can't we are actually seeing ourselves failing first before we utter those words.
