I think you are playing maps that are kinda too high level for you, sure you can clear them but I doubt you will get good accuracy on them before first just playing and getting use to all the types of notes because your accuracy shows that you are mashing the keys. This is all assumptions based on looking through your top ranks which are maps between 4.6 - 5 stars and I am also going by the duration of play and clicks. High acc and FC'ing them will not happen any time soon.
Get use to 3.5 - 4 stars first and get the basis down like 1/2 , 1/4 notes, triples, mini streams etc etc and then try again later.
