If you just want to earn money, go for Machine Learning with Tensorflow and dig deep into Python. Thats very valuable and there's lots of positions for people of all skill levels in this area. Plus it sounds cool at dinnerparties.

Lots of people know Tensorflow and python, but if you can be one of the people that also understands the underlying math and can think about the results in statistical terms, rather than simply treating it as a black box, then you'll be way ahead of the pack.
