You have to be more aggressive. This doesn't mean feed all day, but when the time is right don't be afraid to commit to duels, scout is the best 1v1 class. You have to push these boundaries in scrims to find out what you are capable of.
Sometimes just being alive is the best thing you can do though, it just depends on what else is going on.
Whenever my team is losing, my accuracy is always over 75% because my entire game is just running away trying to stay alive and chip-shotting people. But if there's actually a chance to take fights, i'll get closer to 65-70% because I'm taking more fights with harder to hit, but more rewarding individual shots.
Obviously the real goal is 300 dpm and 75 accuracy, but having 75 accuracy and 160 dpm is symptomatic of an issue.
Or you're just a flank player, and your team is losing every big fight quickly, but even then there's more room to draw attention than you might think.
As an aside, if you always loose your duels and don't know how to stay alive in close range, take some time to play soldier in DM against other scouts and take note of what's most effective against you when you're seeing the fight from another perspective. Also play some scout v scout MGE so you can feel confident when entering that situation, and wont just play it safe every-time. Sometimes just running in and creating a problem is the best thing you can do in a group fight because at least the other team has to acknowledge you exist and deal with the subsequent pressure that brings, just think about how much harder fights are if you have damage indicators coming in from people you aren't focusing on.
Actions you can take to improve:
if you have a fight in which you judge yourself to have the upper hand, simply take the chance and see what happens; this will force you to build an accurate picture of what a good fight looks like to you because you have the required experience. you can also watch demos with the intent of seeing what causes good scouts to want to commit their lives to a kill.
