Here’s a circuit board with resistors installed. They’re used by hobbyists to make their own boards.
However, even for hobbyists, surface mount versions are now common:

Yeah, the first kind is more common when you’re a beginner hobbyist and are just starting to learn to solder just using a run of the mill soldering iron and soldering wire, whilst the second kind at the very least requires some experience soldering and a steady hand, or some special equipment (an over for it and solder paste - which unlike solder wire spoils with time if unused).
However you can make way smaller circuits with the second kind (even if using the bigger surface mount components) plus many integrated circuits only come in surface mount versions.
Also the second kind can be wholly and easilly be assembled by machines (in fact the really small surface mount components are near impossible for humans to properly place), which is why if you open an electronic device nowadays you’ll see it’s almost or even entirelly made up of surface mounted components.
