That are important in playing badminton

You are right, but confidence is important too.

it is important to foresee where the opponent's ball would be and it more important to not let ur opponent know where u are aiming ur ball. footwork counts a lot too. i know this is my problem. i started playing badminton two years ago and i was already 50 by then... and i didn't have to go to a badminton clinic and no formal coaching. all i wanted to do was to sweat it out but it came out that i fell in love with the game, so i am playing up to the present.

Positioning and being able to anticipate your opponents next shot are important. Ball placement is not important as you use a shuttlecock in badminton not a ball.
