True.
The Second Law says the entropy of an isolated system tends to increase, so a highly ordered (low-entropy) state is statistically extremely unlikely to arise from a high-entropy past. That is exactly the puzzle cosmologists face: the early universe had an extraordinarily low entropy (very smooth, low gravitational entropy), and explaining why the initial conditions were that way is an open problem (inflation and other proposals address aspects of it but do not fully remove the difficulty).
