Im 15 years old and i want to race pro soooooo badly but my parents do not support this and i have no money

so that means right now my chances are not looking good.do think it would be possible for me to race pro after starting at about 18.I know there are people that have done this before but it takes alot of natural.I have a a little bit of carting and i am confident in my natural tallent but that does dot neccesarily mean il be good.
Also i do not care about the money.as long as i am making enough to aford an appartment an a car i will be in heaven.I just want to be comppetative in a series
