I made something off every single Hub I written. As for Google Adsense Paycheck, it took me 6 months to get my first $100. Times have been rough because of the Google Search Engine updates over the last 2 years, but I still generate money. I also made money from Amazon, I get more frequent $10-40 checks from them because their payment threshold is only at $10 usd. Its harder to make money with Amazon though, because the end user has to actually buy something where with Google they just have to click.
If you work hard, make a few Hubs and share them everywhere to get them traffic and get going you should be successful too!
