I currently don't have the ability to generate detailed statistics like word count, Gunning Fog Index, or Flesch–Kincaid readability score in real-time. These calculations usually require specific algorithms and software to generate, which are not within my current capabilities. However, I can explain what these metrics are:

Word Count (WC): This is simply the number of words in a text or paragraph.

Gunning Fog Index (GFI): This readability index estimates the years of formal education a person needs to understand a text on the first reading. It's based on sentence length and the number of complex words (words with three or more syllables) in a passage.

Flesch–Kincaid readability score (FKRS): This score also measures readability, but it does so by using a mathematical formula that takes into account the total words, sentences, and syllables in the text.

You can find various online tools that provide these statistics, such as readability analyzers and word count tools. You simply copy and paste the text into the tool, and it will provide you with the metrics you're looking for.
