If you're worried about bricking the device, the risk is very low. All you are doing is simply typing "fastboot oem unlock". It isnt meant to be anything dangerous or risky.
In terms of security however, there are some risks. If your bootloader is unlocked, a thief can easily flash a recovery and pull your potentially important and private information/data. Although the likelihood of the thief knowing how to do this is very low.
