Way too old for allstar cheer right?

So I’m originally from here in North texas at 13 I wanted to do cheer but my mom put me in the cheerleading with poms poms exactly what I didn’t want but when we loved to Indiana I did dance because that’s what they’re strong in but we moved back home and I attend SMU. I wanted to continue dancing but dancing ducks here and would like to try allstar but my only option is open and that’s level 4 so that would take me years in some wildest dream that’s slim to impossible is to one day make a level open team or join SMU cheer in my junior year (I’m a freshman rn). But I have no all star experience because of dance I have a perfect cartwheel, backbend and back walkover (but I lost my back walkover), spike/straight scorpion, scale, arabesque,(but god knows probably I will or won’t even get a flyer position which doesn’t matter to me). I was spotted on my bhs back then. This is all I can do which is like nothing in cheer terms lol. I hope to take tumbling and conditioning classes at Cheer Athletics. The question is will I look like a joke a 20 year old taking classes at Cheer Athletics??😂 (they’re the best so I will feel embarrassed)
