There's a very low probability! - In consumer equipment, much of your RAM is often unused at any given time - Most lines in a cache are eventually thrown away, never used - Did you even save your text file, or just open it to read it? - What about all the space occupied by read-only information, like executables, media files, game files, and libraries? You might crash, but nothing will be written to disk You might get an error a month, but the odds you'll get an error that matters on your average consumer machine with average workloads is much much lower.
