Hello Drako,
I'm not a senior member here on the Forum, but it looks like you have a tremendous amount of support. No one that's honest with themself gets anything out of sh--ting on anyone else's dreams. Nor do I think anyone here would lie to a younger person only to be fooling one's self.
Blacksmithing that does bring in income whether hobby or full time is backed by quite a bit more equipment costs and acquired skill costs than what's on the surface. Education, skills, and equipment all take a substantial portion of one's lifespan to pay for and gather. If ironwork would pay for college it would be coming out of a shop backed up by long earned financial buildup and develpement. That kind of earning power doesn't happen on start-up.
Start slow, practice patience, maybe find a related job in a welding shop to help get started and pay for some classes. Make your decisions with a time built arsenal of knowledge and equipment. Careers go a bit easier with a little more preparation. We all want you to succeed. Good luck
