Look, what the others said is partially true, but there are certainly exceptions.
This summer I was 15, and I interned at Icelantic Skis in Denver, CO, with no prior experience, work, etc... They totally were down to have me and a couple other high schoolers as interns, and none of us really had any prior qualifications. It was awesome, and I'd say just go for it. That being said, I don't know if the same will happen for you based on different location, company, situation, etc... But still, try for anything you can!
