Right, and Unity has a huge customer base. As of 2020 there were over 1.5 million active developers.
Unity says as of June 30th, it has a “global reach” of 2 billion monthly active end users (read: consumers, not developers) adding up to 8 billion hours of gameplay per month, as well as 1.5 million monthly active creators. Those creators developed 8,000 apps and games each month with Unity in the six months prior to June 30th.
And how many "super popular" games made by indie developers can you name? Certainly not 1 million, or even 100K. I mean, without using Google, you could probably name a few dozen at most. So the ratio is not that good. Given that Godot is less established, and much newer, there is a far smaller chance of there being hit recognizable games.
In any case, what other people are doing, or have done, has no relevance. Evaluate the technology available for your use case. Does it have the features you need, are the graphics good enough, is the performance acceptable, is the cost within your budget, does it seem easy to use, is there help available, how is the documentation? Evaluate these things yourself and make your own decision. Most people don't know what the hell they are doing and have no experience, so figure it out yourself. I mean McDonald's is the most popular restaurant in the world, doesn't make it good food.
