I'm trying to export PDF file with crop marks 1mm, but it shows 12mm in exported file.
I cant' affect an output by changing setting in export menu. Can anyone help and explain
why this happens and how can I change it...?
Can you be a bit more specific? I'm not sure what you're talking about.
BTW, a lot of printers don't even want them. The crop / bleed info is included in the exported PDF and they prefer to create their own.
Offset is the distance from the art. Your screenshot looks fine.
I would pick up the phone and get all of this clarified because I believe you are overthinking this.

I think you misunderstand this image. It explains that your InDesign document must measure 172 mm x 55 mm with a bleed of 1 mm. That's all.
Also, in your first capture you’ve exported the bleed area, but your black fill is aligned to the page trim and is not included in the bleed area:
