Illustrator files do not have a resolution, they contain scalable vectors.

Images and raster effects like dropshadows  have a resolution, but the file you showed do not have those.

Unless your printing company cannot print PDF files, you should have no problems with your files.

That means everything is okey with my pdf?

It looks like you started in RGB and later converted to CMYK, which causes your blacks and grays to be made from multiple CMYK inks.

You should contact the printer and show him one of your files.

Okay.Thank you very much. But I created it from begining cmyk color.and 300 ppi. and all images,fonts are vectors

If the file was CMYK, you must have specified your colors in RGB, your text color looks like a rich black, the result from RGB > CMYK.

You were right.. My document I've created CMYK, but font colors I choose RGB. , so now I need to click there (in the picture) and choose color?

It depends on the printing process/printer/printing press if the 4 color black gives a problem.

Small type will become fuzzy when the colors are not printed exactly on top of each other.

Your example contains large type so if printed correctly that should not be a problem.

But you can correct it by selecting some text, choose Select > Same > Fill Color and click the black swatch to replace the colors.
