Welcome to the parrot forum! Glad you found us here!
I think it's very admirable for you to do all the research before choosing to get a parrot. People like yourself who make well planned decisions and make an effort to learn are much more prepared for possible problems like plucking and can do everything possible to try to prevent these things from happening.
Plucking seems to be related to a lack of mental stimulation/interaction, as well as physical/health issues. There's a bit to it, but in summary, if you take your bird to a vet to get a wellness check every once in a rare while (many people do it yearly), give it showers/let it bathe sometimes and keep it mentally stimulated/give it lots of interaction (through training/foraging/keeping it flighted) then you will most likely avoid plucking and self mutilating.
Hope that you enjoy the forum and please post any questions you may have because we have quite a few members who enjoy helping out.
