@kevinsync's answer is 100% correct and it's been this way for the last ~~~20? years? at least - only it was "Photoshop files hold the (design) truth" before - now it's figma.
But yes, the "design to code" gap has always been where designers' intentions were butchered and/or where frontend developers would discover/have to deal with designs that didn't take into account that some strings need more space, or what to do when there are more or less elements in a component, how things should scroll in real life, how things should react to a variety of screen sizes, etc.
this short meme video is funny/not funny because it hits too close to home - https://www.youtube.com/shorts/r6JXc4zfWw4 - but yes, "designers don't code and developers don't design", roughly speaking
and then of course you meet some people who do both really well... but they are pretty rare. :-)
