I did not say that "'suction' plays no or very little role in making lift on a wing", but that suction's role has been exaggerated while pressure on the bottom of the wing has beeen ignored in the past.
While the curve of a sail and the curve of the upper surface of a wing are similar, still one is a sail and the other is a wing and the air flows around them are different.
