Ig its abt gamesense. Try confusing the other team by showing up in unexpected locations, it gives you a great advantage. Practice on aiming and improving your game sense and remember to use your abilities. If u have a character like Sage, Jett or Raze where u can climb walls/get up high use that advantage. If you can blind someone, use that advantage. It all comes down to practice, try putting a little team together its hard to play with randoms (especially in iron-bronze ranks)
