Maybe is some cultural difference, but I consider quite common to live with parents in early 20s.

I lived with mine until 26. I had nor money nor experience to live alone until that.

In CS coding is not the only usefull stuff. Maybe your thing is testing, sysadmin, devops, etc.

In fact, a bit of coding, shell and docker is a good starting point for a devops role.

You’re good, OP. Don’t let exaggerated success stories let you down.
