19M, and I keep running into the problem of being too young when women approach.

Got approached by a cute Colombian girl at a casino I was at with friends. Wasn’t drinking or gambling obviously but she came up to me and I made small talk with her but after she asked me my age she immediately said I was too young. She looked 23-25. Not the first time this was happened, but I’d like it to be the last

Is there a tactic to override this or do I just wait until I’m older?
