Getting out of silver, yes has a lot of luck attached to it. Due to smurfs starting their first matches in silver elo. You get a massive skill range that radically swings games in both directions. You can get that guy that is straight on his way to bronze 5, and the diamond 1 smurf in the same game.
Getting out of bronze, no. That's pretty easy if you're decent at the game.
I got dropped to bronze 2 initially and shot straight up to Silver...2 i think? I maybe dropped 2 games out of 30. Then I started encountering smurf after smurf and complete newbie after complete newbie. Since I dropped out of S2, I have never made it higher than Silver 3 because of mostly bad luck.

End game: Enemy Zyra posts Twitch.tv account "Diamond smurfin' in Silver" is the stream title.
Guy that obviously was banned for toxicity makes new account. Has learned nothing.
Fresh 30 that's barely played the game at all.
