>Stephanie's father gets upset seeing Treeko on its own and asks if it's too late for him to take Treeko and start as a trainer, to which Nurse Joy assures him it's not
Sounds like anyone who didn't start as a trainer as a kid can absolutely get a pokémon and start off on a journey as a trainer regardless of their age in later life. Meaning, I'd absolutely be able to start off as a trainer, if I somehow woke up in the pokémon world.
You really should stop projecting your own inherent failures on something that resists being equated to Anon's experience of the real world.
