Learning how to make games does take years. Sorry if that’s a bummer, but UE4 isn’t going to do that learning for you.
Now if you have specific questions, everyone here will be happy to answer. Stuff like “how to load a JSON file in UE4” can be answered through a 10-minutes search. Specific questions about Blueprints, UI, rendering will be answered as well. You can even go to the unofficial Slack channel for UE4, or the UE4 reddit, or AnswerHUB or this very forum. Hell, I made 70,000 lines of C++ code available to UE4 users needing guidance. People will help you.
You will however also need to help yourself.
