You don't need to win your lane to win
But please just don't lose your lane. If it starts to look bad and you give up a lead early and you know you aren't as strong as your opponent, just play very safely and farm and try to help your team by not dying over and over trying to make LCSBIGPLAYS to get back in it. I would much rather have a teammate who realized he isn't going to win lane and decides to farm under tower rather than die 6 times in laning trying to get every CS and trade.
If you need to sit under tower and farm with abilities, then do that but it is much harder for your team to carry when you think you need to carry laning phase to win. You don't need to always win your lane, but do your best not to lose it.
