You are mathmatically more likely to hit a flush than a straight.
In any poker game involving 5 cards or more here is how it works out.
13 suited cards
13 cards in numerical order.
(ignore the straight flush draw. pretend for this example there is no such thing as a straight flush)

You now have 9 clubs to make a flush or 8 cards to make a straight.
On the final card you are obviously more likely to make your flush.
