Statistics aren't always the most exciting or easily understandable thing you can find on the net or in relationship to trading.
You can't spend your life on the beach with the playmate of your dreams or anyone else for that matter, sipping a drink, without some dedication to the discipline of being successful at something else first.
If trading is a hobby, for you, then skip any thorough examination of statistics, they are not really fun...
If trading is something you would like to know more about than your average trader, it likely will be necessary to understand probabilities and all the rest....
For that matter what are the possibilities of ending up on the beach with the girl in the yellow bikini?
