Airplane ticket help?

I have a flight from san antonio to denver on independence day. Im 14 years old and going by myself, and not getting the unaccompanied minor service on united. The ticket I purchased is an adult one though (age 18-64) but I entered my age and stuff on my travelers info. On the united website it said minors ages 12-17 can travel as adults. Is this a problem?
