No, you are a (we assume) mentally competent adult (have not been adjudged incompetent based on medical evidence of incompetence or had a legal guardian appointed for you); mentally competent adults may do as they like, live where they want, move out or move away whenever they want, etc. Your parents have no legal right to stop you from moving out. If they do something illegal, call the police and press charges for the appropriate criminal act (e.g. using force to restrain you, even just grabbing and holding you, is assault at a minimum; taking money or car keys or phone or something else you need is theft; trying to sabotage your plans by calling up a landlord, pretending to be you, and claiming you changed you mind about renting would be a form of identity theft; etc.). The police should help if illegal or criminal means are used against you.
