I can't imagine it's changed since I used it a few years ago. But it used to be that single tap only took you to a word boundary on iOS. So for example if you were to tap in between 3 and 4 in the text "1234567890", the nearest word boundary would be between " and 1. So you couldn't tap within a word but if you wanted to ditch a word it'd be easy to tap the right side of it to get to its right boundary.
