[Dungeons and Dragons] Is there any reason a group of average citizens can't pick up swords and spellbooks and train to be as skilled as the traveling adventurers?

I've always wondered, what exactly sets the adventurers aside from everyone else? Besides the gear and the skill. I understand it takes a bit of effort or sacrifice or being born into it to learn magic.

Are they special? Chosen by a higher power? Superheroes compared to everyone else that people can aspire to be like but it is physically impossible for a random civilian to achieve that level?

Does being an orphaned loner empower you with the ability to shoot arrows really well?

Anybody can be an adventurer. Anyone can learn magic of some type. Anyone can give their faith to a god and reap power from it. And lots of *common* people do give it a shot.

The problem is, there is an extremely steep learning curve to adventuring, and when you're just starting out there's nobody around to bring you back if you die.
