That can be a large difference. I purchased a 1TB micro sd a while back and it only had 930GB of user storage.
Unfortunately that's the way the rules are for labeling.
I'd be worried with Woot used cards as many Amazon cards(new & used) are counterfeit. People check them when they get to their computer and send them back to Amazon so don't be surprised if they ended up on Woot.

All storage drives after formatting will lose 5-10% of the total capacity. 930GB of usable space is pretty standard for 1TB drives.
Can it be used in dash camera or security camera ?

Drive manufacturers call a terabyte 1,000,000,000,000 bytes (this is the amount of bytes you get on a 1 TB SD card)
Microsoft calls a terabyte 1024 x 1024 x 1024 x 1024 bytes (this is why Windows only shows it as 931 GB)
(See attached disk info screenshot.)
A little more explanation here … https://www.makeuseof.c
Now we know why computers use 1,024 instead of 1,000 to define these common prefixes. To a computer, one kilobyte is 1,024 bytes, not 1,000 bytes as it is to people. This compounds as you move up the scale, so one megabyte is 1,024 kilobytes, and one gigabyte is 1,024 megabytes.
To see how this affects you, say you buy a 250GB external SSD. That disk contains 250,000,000,000 bytes, but the computer doesn't display it that way.
Working backward, we can divide by 1,024 three times (once to convert bytes to kilobytes, again to convert kilobytes to megabytes, and a final time to convert megabytes to gigabytes) to see how much space this actually is:
250,000,000,000 / (1,024 * 1,024 * 1,024) = 232,830,643,653 bytes, or 232.83GB
Examining a 250GB drive in Windows shows its maximum space as 232GB, which is exactly what our above calculation found. That's a difference of about 18GB from the advertised amount.
And the larger the disk is, the bigger the difference between measured space and actual space. For example, a 1TB (1,000GB) disk shows 931GB of space when plugged into a Windows computer.

I would not use this for those applications.
These cards are meant primarily for reading static data that doesn't change often.
i.e. Downloading a game for the Switch. The game files don't change and only need to be read.
Data that needs to be constantly read, written, erased, rewritten, etc like security video will kill cards like this within two months. Go with the high endurance ones for that.
I wish they would list the usable amount on packaging. I've seen a dimwit go full Karen at the att store because they paid extra for the phone with 512 GB and they didn't know that number was before formatting, software,and updates. I assume that lady would do the same thing all over again when buying a memory card. 😆
