Why is sniping so EASY on COD BO6??

(Quick back story: I played COD from MW3 2011- MW 2019. In those games, I would win most private matches Quickscoping, but NEVER used snipers in public matches TDM etc. Because I would instantly get ripped up by SMGs. In 2019 I quit COD for 5 years and missed every cod up until now 2026.)

Today I downloaded black ops 6 on console as I wanted to experience a newer game. I picked the default sniper class at random, thinking to myslef I'm about to get ripped up. But to my surprise, I destroyed basically everyone game after game quickscoping with high sensitivity. Bearing in mind be haven't played for 5 years and never in my life sniped in public matches, why am i demolishing everyone online with the default sniper? Why is it so easy on BO6? What did they do to the game to make quickscoping so easy in public matches? I ending players before they even get to aim at me. Even with SBMM in newer Cods, it shouldn't be this easy since everyones using full auto weaponry. Theres no way I've gotten better because i havent played for 5 years. I looked online but couldn't find an answer to why it's so easy, hence the reddit post.
