This error is so common that most folks will know what you mean. It’ll only really get you in trouble when you’re accurately comparing sizes of storage and data. There’s a good chance it won’t really matter unless you’re working code.

This is also why a “2 TB” hard drive is “smaller than 2 TB.” 2 terabytes is 1.819 tebibytes. Even Windows will call it TB and terabyte, so people have often carried a conspiracy theory that drive manufacturers “short you,” or that the missing data somehow has to do with enormous file system metadata.
