Does just reading helps?

Does just reading helps? All most ever one I ever met have always told me that just reading anything or specificly reading something that is hard to pronounce (for example for me reading Hindi and Sanskrit is hard) will help you overcome your stammering. But the main thing that always discourage me is that most people who fixed their shutter and stammering by reading was when they were kids but for me now I am almost an adult and I am scared as shit to face the real world now that my college life was so hard. So does reading really help?
