Am i doing something wrong?

I have a ryzen 5 5500 CPU, RX 7600 GPU, and 32GB of RAM. I watched a bunch of youtube videos of gaming benchmarks for this build and they were playing a bunch of games perfectly on high and ultra settings in some cases. But when i play the exact same games, using the exact same pc specs from the video, i can only manage medium settings, and im not even using 1080p resolution (i dont have a full HD monitor). What am i doing wrong here? I have the same specs from the video. I mean im comfortable with medium settings but i just dont understand why im not hitting the same marks as the video with the same build.
