#### The reason behind the ranking

The grouping of hands is made upon their probabilities. A hand with low frequency is ranked higher than a hand with higher frequency.

There is a huge difference in frequency between the highest ranked hand, royal straight flush, and the second most common hand, one pair.

But regardless the hand the winnings are not affected. You cannot win more than the pot, therefore, a straight flush doesn’t necessary win a bigger pot than a high card. In reality, a very strong hand such as a full house can win big pots because an opponent with another strong hand such as a flush will be willing to invest a lot in the pot.
