What are the ways of visual programming in UNITY?

Question

Unity

Hi friends!
Decided to learn the Unity engine. For multiple purposes:
1 . Development of 2d games on Android (for starters). But in the future, switch to projects from the 3rd person (3d)
2 . Architectural visualization in real time + VR https://youtu.be/ydUgE-S7Dag
3 . Advertising https://youtu.be/O1uNKwIBHfc
Before asking questions, I will say that there was a difficult choice between Unity / UE4, I will not list all the advantages and disadvantages. Because there is absolutely no knowledge in C++ / C# languages, it didn't matter where to start.
UE4 immediately attracted attention with the Blueprint tool. I know that similar tools have already appeared on UNITY (for example: Timeline ?, Visual scripting, Bolt), in fact, what are the questions:
1 . What are the ways of visual programming in UNITY and is it possible to do without C# knowledge at all? Perhaps my examples are not entirely successful, tell us who uses it, what do you think about this?
2 . Will there be enough knowledge in 3D and Adobe applications in conjunction with visual programming to achieve the three goals?

Answer 1

(I'm writing about units) My opinion is that all this visual programming is not serious and I'm not sure that all tasks can be solved. So learn to write code.
In general terms, a "game" is:
- Idea
- Concept
- Models
- Rigging
- Animation
- Textures
- Light
- Rendering
- Programming
- DB
- sound
- advertising
I may have missed some basic things, but I think this list is quite enough. See if you have enough knowledge or not

Answer 2

There are many ways, but only one is worth using: https://toster.ru/answer?answer_id=1310781#comment...
