Only for uniform probability density. All that's needed is a tendency to sustain itself, instead of diminishing it. This isn't that unusual; consider waves. Structures also spontaneously arise, such as bubbles (foam), crystals, streams, rocks. But if pre-life RNA existed, it would be hard to identify: very small, similar to life detritus, and quickly processed as food.
