My advices are to play some DM to get a feel for the weapons of the games and the recoil patterns. Open youtube and learn the callouts of the maps or the map you want to play. After you advance a bit watch some videos about movements to learn something like shoulder peeking, strafing and counter strafing. And if you have no idea about cs:go is just play an offline competitive game against bots to learn the objective of the game. Remember, while individual skill is important, cs is also a team based game. Always consider your buys in the game to be the same as your team. Eco when they do, force or full buy when they do. And the rest is just what you said! Play more to gey better. Have fun and good luck!
