The goal of the game isn't to win, it's to make sure the enemy doesn't. These are two completely different philosophies. I'll explain in terms you might not understand until you have more experience with the game, but are good to keep in mind nonetheless:
Laning: Your goal is to make sure the enemy laner doesn't snowball. Most of the time you do this by making them unable to farm creeps, and there are 128903719287 different ways to do this.
Teamfights: Your goal is to not die, or at the very least die less than the other team. If you die you are useless. You do this by doing your champion's job in a fight--kill the enemy, make sure the enemy carry can't do damage, take all the damage so your carry doesn't, make it easier for your carry to do damage, etc.
If you play a game thinking "I need this many kills so I can buy this item and kill everything", your main motivation will be greed, you will make stupid aggressive plays, and you have a higher chance of screwing up and dying. If you think, "I need to make sure this Katarina can't farm/roam so she doesn't get these items and kill everyone", you will eventually be stronger than that Katarina if you do your job right, and end up killing everything in the end anyway. Even if you don't succeed 100%, you probably played smarter and cut your losses.
