Confidence that showed up without its homework.

means A lack of the skill, ability, or knowledge needed to do something properly.

from Built from Latin in- ('not') plus competentia ('being fit, capable, or proper'), itself from competere, literally 'to come together, to agree, to be suitable' (com- 'together' + petere 'to seek, aim at, strive for'). So the root idea is of things — or a person's abilities and a task's demands — failing to meet up properly. English picked up 'competence' and its negation in the 1600s, straight from this Latin lineage.
