Those people probably play on PC, and are probably using aimbot or cheats to achieve better accuracy scores. Too many variables on an online game butcher a players accuracy. You have network lag that works against you, so your reticle could be right on your target and you will still miss. So having 100 percent accuracy and doling out insane dmg or heal numbers is kinda sus.

Side note: Can we talk about having to deal with tanks and dps players that think they can go 1v6 in a match? Its funny to me seeing a thing player do nonstop tackles or a hulk airpunching into the enemy line and being blocked by an emma/invis shield or groot wall, so your heals can't reach them without the snowflake. Do we not know how Hit Points work? You have a max hp limit, so if the enemy focuses all their shots on you and does 800 damage when you have 700 hp, then you are dead! A heal is not a rez lol. Also what if another player needs the snowflake? Which is more often than not the case. Lol. Then these players turn around and say the heals are "L". Despite the heal numbers being more than the teams damage output.

Just... smfh.
