Can a designer only work in raster mode?

Question

Design

Maybe my question will seem wild, but I'm a beginner. Well, as a beginner, I know Photoshop very well for raster tasks, I worked a lot in it, I decided to go into design professionally and then I understand that either everything or a lot is done in vector. For example, I downloaded a mob design template. applications, downloaded a new photoshop (ss), opened it, and I see a huge number of vector elements, and I don’t understand at all what to do with them, how to edit, etc., I can’t even edit the text layer, it’s simply not selectable.
Is there any alternative way other than to understand all this? Not trolling if that.

Answer 1

If you want to deal with interfaces, forget about Photoshop, master Sketch or Figma.
And leave Photoshop what he knows how to do well - work with a raster.

Answer 2

For the designer of sites, interfaces, logos:
1. Vector - the main mode of operation (grid, gaps / indents, smooth contours / roundings with Bizier curves, arbitrary scaling and export without quality loss).
2. Raster - auxiliary (basically, small decorative drawn elements, banners, stylized photo screensavers, etc. to design the overall picture).
