The chance of any planet housing life, let alone intelligent, evolved ones, is unfathomably low. But there are so, SO many opportunities for those chances to be overcome that it's also crazy to think there aren't other sentient races.
Let me put it into an analogy. The chances of winning the lottery are terrible. But if you own every lottery ticket in existence, you're bound to have a winner. Earth had a winner. To say that we were the only ones to win in 6 billion years is unfathomable.
