www.,
outube.com/@ChessKidOfficial/playlistsThis channel contains a lot of information that may be useful to you. And in particular there is a playlist "Chess openings".
But I would advise you not to rush into studying openings, but to look at another playlist - "How to Play Chess". You already know a lot of what is explained in this playlist and you can skip some of the videos and concentrate on what you find new and interesting.
Then it would be helpful to get to grips with the "How To Study Chess Tactics" and "Chess Tactics" playlists. The fact is that this is the basis of chess, and if you do not master tactical techniques, no openings will help you.
You can also get acquainted with tactics and practice on this site in the menu Learn ->Practice
All this will take a lot of time, so be patient and persistent.
Good luck!
