What exactly does Provably Fair mean?

The terminology Provably Fair arose from the development of Blockchain technology, of which Bitcoin is based upon.

For the "gamer" it mean a revolution in such never-before-imagined things such as:  a) fair playing, b) accountability, c) guarentee anti-cheating, d) instant payouts, e) public ledger, etc.

These gambling sites allow the public to see how outcomes are based on the gambler's input and a secret number that is disclosed and changed for the next rounds every hour for example. 

This ensures the security to online gamblers to verify if the website's dice roll or card game.

BitLotto was likely the first blockchain based "provably fair". It uses the transaction ID as the "ticket", and the results of a large government-run lottery to determine the winning numbers.

SatoshiDICE  became a blockbuster blockchain method for online gambling. It uses the transaction ID to determine the "lucky number" (between 0 and 65,535. The secret used for determining that lucky number is revealed after the end of the day.

Theory of winning at provably fair games

There is no such thing as TRUE randomness

Provided enough data, patterns arise in seeming random events, even in nature

The idea behind actually beating the house requires that you first heuristically memorize the game flow.

This is evident in games like Baccarat, where you can notice patterns in the gameplay and use that to your advantage, by increasing or decreasing your bets at the most probably fair time.
