Putting in effort and trying your best don’t mean you didn’t get carried/boosted, effort or lack therof has nothing to do with it it’s all about was the end work you put in proportional to the end work others did, if everyone pitched in equally then it’s not boosting but if your best is like 20% of what your mate is doing then you are being carried.
If I try my best in a raid doing a boss but fail, die, and do 1m dps overall when the rest of the raid did 5m I got carried on that boss.
