I more or less said this to my HR director, minus any reference to Trump, when I made a case for promoting me from plant/production line to office work.
I would use a little more tact, and emphasize that despite your lack of experience, you want to do more and you feel you have the drive and skill to succeed in the position to which you wish to be promoted. Remove any political references (you never know how your supervisors or HR people will lean and best not to assume in cases like this). Don't say "Usually the ones who appear to not know much are the ones who do the best jobs because they have to prove themselves." Instead, say that you are ready to prove yourself and feel up to the challenge, that you're willing to learn and put in the hours required to succeed in the position. And kiss the company's ass a little (without being too obvious about it)--don't just make it about you; include how you want to work to help the company more and how you feel this position will allow you to work to your full potential in helping the company succeed. Say that while it's been a privilege working in your current position, you feel you have reached the limits of your potential in that role and are ready to grow with the company, or some shit like that. Hiring directors and HR people often love that sort of shit if you aren't too fake about it.
Read some books like The Art of War and The 48 Laws of Power. There's some good practical advice in the latter, for instance,
never outshine the master. Talk up yourself and your skills and knowledge in a way that does't make your superior(s) appear to know less than you. This was a hard one for me to learn, as I tend to prefer honesty and truth, but there's a way of making yourself shine without making your bosses look like incompetent morons (even if they actually are incompetent morons). Like, if your boss's boss compliments you on a job well done in front of your boss, don't take full credit, reference your boss's hard work too, but not in a way that makes you look like an obvious brown noser. This law is especially good advice if you're interviewing for intercompany promotions, as you don't want to bitch about your current department head to the head of the department you're applying to, as that dep't head might assume you'll do the same for him or her behind their back. Bad for morale, y'know? Someone like Trump can get away with talking shit like that because he's had the good fortune of being THE MASTER in most enterprises in which he's been involved. Don't assume that sort of bluster and presumptive assholery will work for you.
Don't do the following:
