Gross imports only add up to 14% of US GDP. Is it possible everyone is blowing out of proportion the impact that tariffs will have on the US economy?

So obviously the consensus is that tariffs will devastate the US economy because we’re so reliant on imports. So I was curious how much the US actually imports and was surprised to see gross imports only add up to 14% of our GDP, meaning 86% of our domestic economy is entirely domestically produced.

So obviously tariffs will hurt that 14% and will have secondary effects. But is it possible this is why major investors aren’t worried?
