And for education (e.g., textbooks) and a lot of technical documentation.
Basically any job where you may have to type math (and make it look okay), (La)TeX will be the standard.
Anything other than TeX, LaTeX or Typst for typesetting math would be pure masochism.
But if your job is to actually do things applied, and your math can be limited to scribbling on a whiteboard or a notebook and never showing anyone other than maybe a coworker or two, you will probably never have a need for LaTeX.
