you seem really new to the game and i don't think there's any point to ask if you are good. nobody is good when they are so new.
pp/perfomance points are the closest thing you get to an estimation of how good you are as a player, from the game. people play and focus on differend things in this game, so a single number is a pretty bad way to compare people.
focus on clicking the circles better and try to learn things you want to be able to do. learn/make up the terminology and words for things that relate to playing. hard to learn something if you don't know what it's called.
