Am I too old for a dual training program as a chemical laboratory technician?

A little about me. I'm 23 years old and received my intermediate school leaving certificate (Mittlere Reife) with qualification in 2018. I then went to the upper secondary school (Gymnasium) to get my Abitur (university entrance qualification). This didn't work out; I have neither a Fachabitur (university entrance qualification) nor a general higher education entrance qualification (Abitur). Anyway, after graduating from upper secondary school in 2022, I applied for various chemical laboratory technician and chemical technician apprenticeships, but unfortunately without success. When I subsequently started an apprenticeship in the commercial sector, since I didn't get a position as a chemical laboratory technician or chemical technician, I stopped applying. However, my professional interest remains in chemistry and other natural sciences and didn't fade during my apprenticeship. Now I'm reading in many forums that age plays a role and chemical companies prefer to hire someone younger than someone a little older. Since the competition is already fierce enough, this makes me more skeptical than usual. Is there still a chance of getting an apprenticeship as a chemical laboratory technician?
