Not in undergrad (a single upper division class), but yes in grad school. I did a lot of applied mathematics in undergrad and only took the min required upper division probability/stats class. I didn't find it interesting at the time. But when I got to Econ grad school there was a massive focus on econometrics, and I learned it from first principals.

For languages: SAS in undergrad econ/Matlab for math classes, STATA primarily in grad school, and I pivoted to R and then python when I hit industry.
