I think the difference is I've been able to launch my own digital products before, in the wordpress space from scratch to launch day (wrote the sales copy and built the sites including the back end).
I'd say I am a self-taught wordpress developer and designer, but having launched digital products before, the experience taught me the value of copywriting/marketing. It's also a space I love learning about. That's why even though I can design wordpress sites, I still believe copy plays an important role in web sites, especially in creating funnels.
