One way to get experience is to volunteer. Through volunteering, you can learn new things and make contacts. In fact, volunteering/unpaid/ placements/internships paid and unpaid have become part of the journey of 1,000 miles to finding your path to right employment.
As for the experience game, yes employers always say they want experience. They hold it as a selection criterion to screen you out. they have so many applicants.
With a graduate degree in my field I still run up against the experience factor. They can pick who they want. What you have to do is demonstrate transferable skills, good attitude, reliability, intelligence and likeability. Perhaps there are things you did in highschool (extra curricular activities) that can demonstrate for example a basic set of interpersonal skills or the ability to work with others. I mean how hard can it be to flip burgers or make sandwiches or coffee.
I offer the following suggestions:
*tell everyone you know, friends and family that you are looking. You never know when one day your friend's workplace will need someone and rather than going through a lengthy cattle call hiring procedure ( a pain for most employers), you can be in their face.
*In your community Investigate internships/co-op/volunteer programs geared for youth.
*Consider additional schooling, especially programs that might have placements or co-ops.
