This makes the article correct (although makes no allowance for sampling error, nor for overfitting the available data). Even so, I still dislike the use of this figure, as ROC AUC overstates a poor score: it hints at the model being correct 67% of the time. In fact, the model is only knowledgeably correct 33% of the time, and just guessing the rest (taking its binary-choice 'score' up to 67%).
