If I freeze my credit, it meant no one can see my credit report?

so, here is my thought on freezing my credit report. If once I request all three credit bureaus to freeze my credit, that means no one can apply a new credit line, unless I thaw the credit I once freeze it with a personal pin number I made. Is that also mean that no one else to see or look into my credit report from all three credit bureaus too? I also wonder how much it will cost to freeze a credit report in your state, and how much it will cost to thaw it?
