Is it worth learning Unity?

Question

JavaScript

I plan to develop games for mobile devices.
Initially I thought to learn all related languages ​​and development environments.
But today I came across this video from the Unity team. Its quality impressed me and I decided to learn more about this engine. As I understand it, you can only know one language to work with it - and this makes it possible to develop for any device. Do I get it right?
And is it worth it to start learning Unity now? If so, what resources are available for this? (preferably in Russian)
Thank you.
