If I turn off sync library, and then cancel Apple music, will the remaining tracks and playlists be deleted? (Curse of a trial)

So I’m an aspiring DJ and have spent a massive amount of time downloading tracks (none of which were from the Apple Store) and creating playlists. I saw the free trial for Apple Music and thought why not, it’s just a trial. I did not realize they now essentially own my music and I will lose all of it and all my playlists unless I decide to start paying for the service forever. Im hearing conflicting things though like music not purchased from Apple, will stay on your computer or original device. But that you will lose all of your playlists? Even the ones made before the trial?I need some clear answers cause I spent so much time collecting and creating my music library and I don’t really wanna keep Apple Music, but I really don’t want to lose my music/playlists. I turned off “sync library” a few days ago, I’m wondering if I cancel the service, will those tracks and playlists that remain after turning off sync library be deleted? Again I bought none of my music through Apple and all the tracks are downloaded on my laptop. I just want to go back to how it was before this curse of a trial. I appreciate anyone who takes the time to read this and might have answers for me. Sincerely
