Morphology
The meaning 'an unpredictable or unforeseen event with extreme consequences' is a metaphorical, domain-specific sense that cannot be compositionally derived from 'black' (a color) + 'swan' (a bird); a B1 learner who knows the two words would most likely interpret it literally. Although the metaphor has become widespread in higher-level discourse, its idiomatic sense (coined by Taleb) is not predictable from the constituents and requires prior exposure.
Etymology
Black swan comes from a surprising real bird: people long thought all swans were white until explorers found black ones in Australia. That discovery made black swan an image of a 'very rare and unexpected' event that can have big effects.
