The probabilities are not normalized, but can be normalized when calling the calibration_curve() function by setting the ‘normalize‘ argument to ‘True‘.
WebThis function calculates decision curves, which are estimates of the standardized net benefit by the probability threshold used to categorize observations as 'high risk.'. Curves can be estimated using data from an observational cohort (default), or from case-control studies when an estimate of the population outcome prevalence is available.

If your classifier produces only factor outcomes (only labels) without scores, you still can draw a ROC curve. However, this ROC curve is only a point.
