So I was talked out of ROTC when I was in high school because I had a good GPA and my parents wanted me to make a good (peaceful) living. Anyways, I graduated today and I still have the ambition to be a fighter pilot as I did when I was younger. I'm 22 now and graduated with a Finance major from FSU with a good GPA, is it too late for me? I love aviation and would love to serve my country.

For the active duty AF, you can try for OTS and a pilot slot out of there. The odds aren't great, but they aren't zero. Guard and Reserve units have a different process (that I am unfamiliar with), but can end up with a pilot slot.

Of course the USN and USMC also have fighters, but I don't know about their commissioning and selection programs.
