No. Approximately 79% of Klondike Solitaire games are theoretically winnable with perfect play, but most players win about 25-30% of games. The deal of the cards determines whether a game is solvable.
Key strategies include: always move Aces and Twos to foundations immediately, expose hidden cards in the largest piles first, keep tableau columns balanced, don't empty a column unless you have a King to place there, and don't draw from stock until you've made all possible tableau moves.
