3 of the weakest players easily stand a chance to stand toe to toe with the absolute best players, and do so without losses- 3 guns is 3x the damage output if you can all establish line of sight at the same time (takes practice but mostly just *be aware of your surroundings*) and 3x the health. Even the worst players can kill the best if they work together, and teamplay and properly working together is the absolute most fundamental thing you can do to increase your pushing power, even moreso than just getting good- two good players working together is what results in 10-0 games
Focus on working with other people who know you're working together, cover each other's backs, and properly moving as a group will make the games way more tolerable for a player with poor aim, especially if you have one good or directed player with the group who actually can point you around or give you tips to leech off of. It might take active effort, it might be waah tryhard, but it's the fastest and easiest way to improve. 

General plays are all controlled ultimately by communication, but there's still stuff you can do if you refuse to unmute your mic. Figuring out maps beforehand is obviously a huge advantage, as you have to know at least the general layout to avoid wandering aimlessly. Moreso than that, watching angles, determining where enemies are approaching from or how many are defending a certain site, and figuring out good ways to defend your bombsite are all huge levers that good players exploit out of pure muscle memory. The most simple of them is just hearing tons of footsteps approaching you, or seeing 8 guys on A-site and going to B instead. Just know when and where to fight, and how to exploit that, instead of running into a meat grinder because you're already too dedicated to turn around. The most common of these is as T on dust 2, and watching mid to determine how many cross over to B-site. Counting CTs means you can choose the less populated site.
