As far as I know, new players start with silver V MMR. That means they don't even interact with you personally at all.
You definitely can carry yourself out. Even if your personal skill only translates to a 55% winrate, that will eventually get you out. Lets look at your recent games. If you deserve to be out you should be doing well and your teammates are dragging you down right?
At the time of writing:
Fizz game: You have 112 cs in a 27m game. 4 cs/minute average. That is really awful. You only had 1 item and t2 boots at almost 30m even with 4 kills. You also died 7 times. You allowed your lane opponent to roam and get a ton of kills/tower kills (I'm assuming Anivia was your opponent since Talon has TP). You were part of the reason your team lost
Lux: 200cs in 60 minutes. 3/minute. That is 60 gold per minute excluding passive gold, and means you miss Nine out of the 12/13 (cannon wave) minions that come down your lane. with 20CS being roughly equivalent to a kill, it quickly becomes apparent how much gold that is. every 2 minutes, you miss the same amount of gold as a kill. Some of that will be because of zoning from your opponents and pressure of course, but not so much that you only get 3, especially on a long range, safe mage like Lux. You also have 14 deaths. That is roughly 4,200 gold you gave them. On someone as safe as Lux that is unacceptable, especially when it was the second highest on your team, only bested by your frontline, Darius.
Fizz (2): 200cs in 55m. 3.6/minute. Still poor, it seems like you just need to improve that. Silver players have around 4-6. That means they will have much more gold than you even with no kills/deaths lane, and will get progressively harder for you to do anything. While you did get a lot of kills this game, you also died a lot for them (12 times), and didn't push objectives with your lead. Sometimes that was because you were dead too, and other times you got kills then you must've either recalled or simply not pushed the objective. Use your lead to get towers and get your teammates fed. Lets say they are holding you back as a hypothetical. They're straight up worse than their opponents. Get them tower/assist gold so that they have the items to compensate for being worse. If they're up 2k gold, it doesn't matter that they're worse.
