You can’t go wrong with a career in statistics. Most statisticians start out with a degree in maths but some of the best I’ve known started off as biochemists or economists or in some other area, and then have retrained as statisticians. Since they have an understanding of a particular problem domain they can have an advantage in analysing data in that area.
But it is important to remember that statistics is not simply a branch of mathematics. You get 13 year old prodigies in mathematics but not in statistics because to be a good statistician you need to understand more than the mathematics. I know many first class mathematicians who simply cannot do statistics.
