Q:

Are AAA games still made with programming languages?

I've been interested in how AAA games are made recently.I looked up how Fallout 4, one of my favourite games, was made. It turns out bethesda games uses a drag-and-drop style engine with maybe a little bit of scripting here and there, like Unity or Unreal. I also looked up how GTA 5 was made. It turns out that rockstar games has its own engine,  Rockstar advanced game engine (R.A.G.E). Slightly disappointed , I'm just wondering whether any AAA game out there is still actually programmed with code. I know that the engine is probably made with code, and if a game company has its own libraries with useful functions/classes that makes sense, since some things will be very tedious to directly repeat. But do AAA industries still use proper code for the actual game? 

A:

Yes, absolutely.
Fallout 4 was not made entirely with Bethesda's drop-and-drop tools. Nor was GTA. Even if they were, that means those games could not be made without those tools, and how do you think those tools came about?
Somebody wrote them. In a programming language.
The engines your thinking of here do a lot of things. Among those things is provide high level tools (such as drop-and-drop scripting tools) that can be used to prototype gameplay and related systems, iterate on them quickly, or allow non-technical developers (like designers or artists) to affect change in game systems without needing a programmer to intervene. 
But programmers wrote those systems in programming languages in the first place. Further, as with most any abstraction, these systems introduce extra complexity which can negatively impact performance, and so they are often not used (outside of prototyping) for extreme time-critical aspects of the game (even the gameplay code). You will not find the core rendering loop driven by Blueprint in Unreal, for example. Nor will you find the kernel of the physics simulation in Fallout 4's drag-and-drop system.
Programming languages are still very much a thing.
