Hello! In most cases classes store base class props, while in fact use some subclasses of those first. So you need just to check, what exact class is used by your object and check its code.
First of all, I don’t have formal studies of programming nor CS.
According to this question "Goto defintion" option for BP nodes does nothing - Blueprint - Unreal Engine Forums to the code of the blocks “is running” or “is moving on ground” I should search for the files “BrainComponent” and “NavMovementComponent” respectively but the code I found are just function definitions that always return false.
Where do those functions return “true”?
