Droid Maxx updates of unwanted apps

Please pardon dumb questions--I am new--but my android came with many apps I do not want. NFL and Ingress are examples. I have read that it is unwise to uninstall these factory installed apps. I noticed the latest Ingress update needed access to my in-app purchases data, which seems innocent enough on the face of it but might it put a hacker in an easier position from which to reach real--not gaming--financial or personal data?
