I would argue you seem to be making decent progress based on your recent activity. At this level it's best to just get the basics down one by one
base speed movement (this is mostly taught in cup difficulties or a lot of 1* maps, you can keep practicing these until you can play most if not all of them well, ideally fcing or getting low miss counts. not much is really required at this level, no dashes are expected at this point so no need to stress about these)
dashing (taught more on salad difficulties or 2* maps, I can't really say there's a true way of knowing how to time your dashes it's one of those things that comes to you instinctively as you practice them more however it should usually be fairly obvious as indicated by noticeably larger gaps, the rhythm of the particular song could also be used as a aid.)
hyperdashes (don't worry about this for now, it's doesn't become important until later but is at least worth understanding how it works, fruits appearing with a red outline gives a speed boost when holding dash for even tighter gaps)
Just keep practicing with the intention of becoming marginally better after each session and you should see improvement eventually. Chances are you are not going to see immediately results but don't let that discourage you.
