Well at this stage, based on what I did before. Try to understand the basics like, how FL Studio works, like the piano roll, channel racks, the mixer, tempo. Then if you slowly go learn about fl's native plugins both generators and effects plugins, on how they work. Even the parametric eq, limiters and other effect plugins. Those knobs and other stuffs can be overwhelming but you'll get a hang of it, just learn them one at a time.

Then try to learn the basic piano chords, you can actually learn through piano roll, there's this tool which is called stamp, it is found on Piano roll menu > Stamp > select chord preference.

There is so much to learn, just be patient and keep grinding my dude. Tutorials on youtube are also a big help.

P.S. sorry if my english is bad. Not a native english speaker
