Both KittehMaster and Hyper ch  are correct, they are both just saying different things.

KittehMaster is saying the more times you try, the likely hood of not getting one becomes smaller.

Hyper ch is saying that the probability of head individual trial remains the same.

A good way to demonstrate this would be to say I was flipping a coin 5 time. In the first 4 flips the coin came up Heads. Most people in this situation would say that Tails was "due" because in the long run the result should be 50% Heads and 50% Tails (assuming infinite trials). However, in each individual flip of the coin, the probability of Heads is always 50%. This is because the events are independent and hence are not affected by the previous trials.
