How difficult is it to become a police officer

I’m in my final year of completing my bachelor’s degree, and with how bad the job market is, I’ve been really reflecting on what I want to do. I’ve realized that I can’t do a job that requires me to be stationary for eight hours a day — I need work that keeps me mobile. I’ve wanted to be a police officer since I was a kid, but my parents never supported it because of the nature of the job. Now I’ve realized that it’s what I truly want to do, but I’ve heard it’s incredibly competitive to get in. For reference, I have some experience, but it’s mostly internship experience geared toward a career in data analytics, so I’m not sure if that will help my chances when applying to the force. Is there anything else I can do to boost my chances of getting in. I also heard that if you’re not a white male you might have a slighter chance of being selected, but I do now know the validity behind it. Also one more question for people already on force, I recently got a fine for accidentally not tapping on the go when catching the train to attend my class. Will that hurt my chances of being a solid candidate?
