Intelligence is the ability for and speed of processing new information, at least as it's measured by metrics like IQ.

Sometimes AI/ML is directly modeled after human/animal thinking (decision trees, neural networks, reinforcement learning) and sometimes it's not (Bayes' theorem, regression, general stats). What constitutes intelligence still boils down to being able to correctly and quickly process new incoming information based on prior information. I believe it definitely qualifies.
