I took the ML class in Autumn quarter and the AI class in Winter quarter of last year, there is definitely a lot of overlap - although to that extent, it might make it easier since you won't have two disjoint topic sets to study. ML definitely goes into more mathematical rigor, while AI tends to cover a wide range of topics in enough depth to know when to apply them and how to interpret results.
