As someone who also possesses an unused advanced maths degree, I would suggest pursuing mathematics for the sheer fun of it first and then decide in a year if you really want to be involved in statistical modeling, ML, deep learning or whatever.

You may end up deciding that being an insurance actuary is the right challenge: there are multiple exams to pass involving a lot of maths and the pay is quite good.

For recreational maths I’d recommend rereading Polya and playing with “Crossing the River with Dogs” and “Math Recess”.

In financial capitals, actuaries are amongst the top earners on par with lawyers.
