Cross validation 'runs several times' but it only predicts each case one time. In your example of 10-fold cross-validation on 160 cases, each of the 10 runs (folds) leaves out 10% of the cases (lets say cases #1-16) to be tested on while training on the remaining 90% (#17-160 cases). The trained model tests on the 16 cases in the hold-out ...
