Trying to prgress

Hello all, first post here, I'm trying to grow in skill. I can learn most songs from YouTube, I know all of the basic chords and I've started trying to improve solo. I have hit a wall, I don't know any progressions or scales, I don't know any structured practices or warm ups and I am unable to just jam with people. Any time I look for resources online to get this structure and try to learn it's a video for those who have never touched a guitar or a video of someone trying to sell a course. Could you point me in the right direction, any advice and resources would be greatly appreciated!
