I recently commited a crime for theft ($56). I am an adolecent, first offence. I was not informed of my rights, can my charge get dropped?

I was at Kohls and I stole a case and headphones reaching 56 dollars. one of the dumbest decisions I have ever made. I am 14 years of age, and I was detained. But, when I was detained the officers failed to inform me of my rights, which I think is a direct violation. Although, they have the video of me stealing. After I was detained, and put inside the vehicle, they began to talk to me asking me why I commited the crime, was it my first time, etc. Yet, again they failed to inform me of my Miranda rights.
