Morphology
The meaning 'a classifier that assigns probabilities to classes' follows directly from combining 'probabilistic' (based on probability) with 'classifier' (a model that assigns categories). The adjective+noun composition is fully compositional and cross-linguistically common, so a B1 learner who knows both constituents would readily infer the MWE meaning.
Etymology
The term probabilistic classifier brings a simple image: imagine a weather person who does not say just 'rain' or 'no rain' but gives a percent chance for each result. The word probabilistic points to 'chance' and classifier to something that sorts items into groups, so the name means a model that gives the chance for each class instead of 'one fixed answer'.
