If I could go back and do it all again, I'd definitely do more stats courses.

Also if you're interested in data science in general, some basic linguistics (syntax/semantics) would be useful. (Saying this as someone with a PhD in natural language processing, who had to self-learn all the linguistic background the hard way)

Our CSE program had two statistic courses required. I feel statistics will be a great skill-set regardless of area of study.

If it's a requirement, take some advanced stats. Take 3 or 4 of them. It's an invaluable skill.
