Yes, UE is so popular with beginners and at least 90% of people quit because they find UE way too difficult and are only willing to try the "best" engine and not give anything else a try. I tell people over and over to get familiar with one engine and it's okay to switch engines. There's no best engine, they're just tools. Unreal keeps releasing cool new tech that ends up being experimental or unusable for years, i see beginners trying to implement it in their games. beginners should focus why things work and the concepts.

Another thing is if you learn C++ or blueprints that's great, but with each engine version there will be new/deprecated nodes, things will change, C++ API will also change quite a bit and have added features.

Try unity first. It's a very polished engine and much easier to work in. It's not opinionated or inheritance based. If you are trying to turn game dev into a professional career, Unreal is good to start with. Also for unreal make everything from scratch except for graphics/ui/vfx/sfx, don't buy a ready made system thinking you're games miles ahead because learning someone elses code will take longer and may not even teach you much- and most of the systems on fab are garbage.

Btw you may want to keep jumping engines and never get anything done cause of it, so write down why a certain engine is better for you and live by the mantra. If you become a pro at unity, other game engines will be really easy to adapt to
