Could I go to Juvie for This?

I was on a website called Noble Collection.com looking at Harry potter wands I saw one I liked so I decided to goof around and pretend to buy it. I typed in all the purchasing information then I guessed on a random credit card number. I clicked purchase expecting it to say the credit card number did not exist but it said thanks for shopping with us your wand will arrive in 5-7 days. I accidentally guessed a correct credit card number that belongs to some random person. I did not mean to buy the toy I'm only 13 years old and I'm really scared and upset now. I don't want to go to juvie I made a very stupid mistake. I don't know what to do now.
