Does Stockfish provide the best opening?

When using the Analysis feature on lichess with the highest level stockfish I noticed that it often, if not always, chooses King's Pawn type of opening for white.

Is it choosing that because it has the highest win/loss ratio?  

Are it's initial choices based on what it has experienced?  If that makes any sense.
