I have an idea and a dream, but I can't realize something with money and knowledge, so I'm looking for a teacher who will teach me how to create a game in the future, when I earn money, I will repay this person personally. I want to create a serious project myself. I am from Russia.

There is no sacred knowledge or shortcuts that teachers can give you. All the basic information is free and accessible. All that is required from you is motivation and self-discipline.

Once you get comfortable with the tools, participate in game jams. There you will be able to naturally gain knowledge through communication with more experienced developers, as well as feedback on your games. Also, in live development, you will be able to understand what specific things you like, what works well for you and is worth more active study.
