That is exactly how the real world works, if you're not good at something, someone better than you will get the job. You improve by playing better competition not by limiting your opponents just your own standard.
Imagine football leagues saying the top 4 teams are only allowed to play against each other because it's not enjoyable for the lower teams to get ripped apart every time they play them. Doesn't happen, I love playing better players as it's the only way I get better when they make me see my mistakes etc. If, when I started gaming, I only played against my caliber of player back then, I'd be no where near as good as I am now.
Time to kill is the same for everyone regardless of being pro or not, the fact remains I'm not a pro and can kill people in less than a clip and have never been turned on by someone who I've had the drop on, maybe your perception of what's happening on screen isn't actually what's happening? Maybe only one shot from 4 are hitting but because the hit markers stay up for around the same time as it takes to fire 4 shots you take that 1 hit marker as meaning you hit every shot in that spray when in actual fact you hit 1 of 4. I don't know, but again, it's a perfect time to kill, and for the person saying ttk on Titanfall was perfect, this game is called apex legends, not Titanfall 2.
