If the context around the number is that it is stored in a .mkv file with a name that looks like a Disney property, or a .key file attached to a program that uses such things for some kind of encryption the government unwisely bans, well, the number suddenly has context around it that makes an argument about the number and the context.

Same for words, really. Words about a threat to a government leader are probably fine in a text file that looks like a short story. Those same words in combination with a history of advocating violent revolution, &c. might make for a different argument.
