I'm 30. making game art for 11 years :

dozens of environments,
thousands of props,
thousands of sketches,
just a few characters (it's hard!)
55 dioramas,
handful of tutorials,
1 finished project ;)

Joined Sketchfab masters in 2022, finished music school in 2015, graduated civil engineering in 2018, recently trying to lead an artistic collab. It worked!
