Hey... my question is, is it possible to get a full ride scholarship out of state under the age of 18?

you have to have either an outstanding athletic ability, win a national merit scholarship, or a major competitive prize for high schoolers.

Yes it is possible. Scholarships usually do not require a student to be certain age. Some may require you to be an incoming freshman. You game has nothing to do with it.

Age has nothing to do with it. The financial aid offer that a school offers you depends on two things- your financial need (as demonstrated through the FAFSA form) and how much they want you. My daughter got offers ranging from 0 to an almost full ride by a private school that was seeking to expand their out of state representation, and their number of women majoring in STEM subjects. 

i would talk to financial aids about it

I don't know what your age has to do with it.  Or what being out-of-state necessarily has to do with it either.  Most all scholarships are applied for during your senior year of high school, whatever age you are at that point.  Full-ride scholarships are reserved for the most academically gifted students and for some athletically gifted student athletes. Sometimes athletes are made scholarship offers before their senior year in an attempt to lock them in to the college or university.  But it's exceptionally rare that academic/merit scholarships would be offered in advance like that. 

Some students do receive a "full ride" aside from scholarships because they might also qualify for grants or other forms of need-based aid.  That's also not related to age, and might only be marginally related to your out-of-state status.
