First off that is great that you have so many interests! I cannot tell you what career you should choose, but I'll provide you with options that you may want to consider and ultimately make a decision yourself.
Just within looking at the scope of integrating sports and stats you may want to be a analyst for data collection service, an independent statistical consultant, team statistician, world tour statistician. These are the results I received after one attempt at a search engine AND I found all of this in the 1st website I clicked. It's nice for you that stats and business have been integrated in many positions that exist. I encourage you to use your imagination and do a little bit of researching. Look up in a search engine variations of your interests in terms of careers that exist. What is also helpful is that once you find a general job position you can then think about how that job position can be used in different environments. So I have outlined statistical consultant for sports teams, but maybe you would rather be an insurance consultant instead?
Also if you want to have even more options, you can look at careers in solely business or stats etc. You may want to be an accountant? However I believe the more well rounded you are the better. To be honest in the current state it would be difficult to find a job in which you solely focused on one of your interests. Usually jobs at the core consist mostly of stats lets say, but they will combine other areas as well.
Statistics are great because they are needed everywhere. They are needed in industrial companies, the weather, research labs etc. A lot of individuals find statistics challenging so if it is something that comes easy to you I think it wouldn't be a bad idea to play on the strengths you already have!
All the best!
