Not exactly. A judgment liquidates the amount of one's claim, but standing alone does not establish a priority higher than what one had before the judgment, which means if you were unsecured before the judgment, you are still unsecured after the judgment IF THAT IS ALL YOU DO. Now if you avail yourself of a post-judgment remedy like garnishing a bank account, and if the bank does not set-off its own claims, and if there is not a senior secured creditor holding a perfected security interest, then you would be a secured creditor. What makes you a secured creditor is achieving a non-consensual lien by getting through all the hoops. And that still puts you behind the consensual lien holders like secured creditors who are properly perfected. Long shot? Maybe. But doing nothing leaves you only with a distribution from a bankruptcy estate - pennies on the dollar or nothing.
