No it isn't, that's not what appeal to authority means. An appeal to authority is using someone's perceived authority to support an argument, i.e. "Actually you're wrong, because Elon Musk says" or "Um, no, do you have a PhD in this, like I do?" or some other attempt to override argument with the trappings of success rather than actual merit. I know this because I have a Masters Degree.
