Thermal pastes job is to fill any imperfections etc to make proper contact.
Now, I've never seen noticeable grooves in a coolers plate, but it shouldn't impact it's functionality.

You'd want to clear it out though (paper towel, coffee filter etc) and a new application would fill in the slight grooves.

I can't clean it out, the little grooves are so small and tiny that I can't. Would it cause an issue if I can't clean it out?
