You should use tools that are appropriate to what you intend to achieve. If you want to make a 3D game then Unreal, Unity, or Godot are appropriate choices. If you want to make a 2D game then something like MonoGame might make more sense than Unreal. You don't need highly refined netcode if your game never needs to exchange data in realtime.

Heck, I've seen someone build a visual novel-type game with WinForms. That was actually a sensible choice for the game's presentation and interaction needs.

Of course if you want to become a game dev at a studio then you should be competent with whatever the studio uses (or something comparable so you can pivot to their stack). If you only want to make your hobby project and maybe publish it later it doesn't matter if your engine is Unreal, MonoGame, RPG Maker 2000, or vanilla JS/DOM.
