As per my undestanding it is prediction percentage based on your proposed model, the true percentage is depends on ground truth data (gold data) recomended/verified by respective data experts.
In one terms, you can look for sensitivity (true positive rate) and specificity (true negative rate) or accuracy or PPV etc.
