Right now the way the current League system is structured, rank actually doesn't mean much in terms of individual skill, it just means you win a lot (I honestly think rank is just for style for a lot of players). Of course, people at Diamond/Challenger tend to be better players (more map awareness, better game sense, etc.). However, I've seen Silver and Gold players beat Plat and Diamond players, so rank doesn't mean everything.

If you're looking to climb the ladder, though, it does depend on your individual skill and ability to carry if your team is slacking, but it also depends on your team's ability to play well (not feed, play safe, ward, etc.). My recommendation is to learn a few champions for each role so you can play anything on the team rather than stick to one role. Of course, you can main a certain position but it is always good to know how to play each position. I would also duo queue with a friend who you know is relatively skilled so you don't have to worry about one person feeding. With practice, finding and eliminating your mistakes, and polishing your skills as a player, it's possible to reach gold, plat, diamond.
