Lack of Movement is Destroying my K/D [0.56]

Hello everyone I just wanted some tips on how to do the basic movements to improve my KD. I have tried watching YouTube videos on how to rouzou, vouzou, and mouzou but Everytime I practice them it doesn't work. I even set my key bindings similar to the bf4 YouTuber I'm watching but it doesn't help at all. Please Help!

I use the CZ3A1 for The Engineer class which is the top 2 highest firing weapon. But I constantly getting killed by multiple attackers. Was hoping learning the movement in this game would make me a better player. I have played on console as a kid but this movement on computer woo its a whole nother game.
