Possible to use any I/O PIN for GPIO? (re: STM32, etc)

I'm new to micro controllers (but I have a software engineering background) and I decided to purchase a NUCLEO-F429ZI (STM32F429ZI).There are a LOT of pins on this board (168 I/O pins according to the datasheet!). However, if I just want simple HIGH/...
