There is a difference between doing your job and getting carried.
A lot of people seem to think that if you don't get hyperfed in laning phase, you just got carried. For example, going 0/0/0 in lane and then start doing your job in teamfights is not getting carried. Neither is playing support and doing decently. Even if you lose lane, as long as you start doing your job for the team, it is not getting carried. Getting carried is you going 0/5+/0 in lane and constantly making bad decisions, yet you still win.
