14 day ban question

Hello, Yesterday i got a 14 day ban, yes i was being toxic and got really out of my mind (antisocial personality disorder so im very impulsive), so i admit to that. I realized i can't screw up more since ill get perma banned so im gonna keep my hands off the chat. What im wondering is the ban said i'll need to prove myself after the ban to get rewards again, what does that exactly mean? Will i not get my champions, profile pics and w/e after my ban has ended?
