Oh, like… all of them? Not quite, no. There were about…500 to 600 different Native nations in North America, I think, plus more in Mesoamerica and South America? Across a huge diversity of different landscapes. Some of them were nomadic hunter-gatherers, a few were settled hunter-gatherers, but a very large amount of Native nations were agricultural and either settled in one place year round or had a winter and summer home deal where they transited between the two. A huge amount of foods that are now well established worldwide were bred in the Americas as agricultural crops, including corn, many varieties of beans, tomatoes, potatoes, a number of squashes, and sunflowers. There were several heavily populated urban centers as well – check out the Inca, the Maya, the Aztecs, and in North America the Mississippian Mound Building culture, and the Pueblo culture for examples of heavily populated cities. The Iroquois/Haudenosaunee Confederacy also were settled agriculturalists, though I believe they also did have substantial hunting and gathering activity (agriculturalist vs. hunter/gatherer is more of a spectrum than a binary choice) and I don’t believe they had population centers that were true large urban centers like the other examples I listed.

Not to mention when the Europeans arrived they found massive cities that had running water, sanitation workers, and a relatively clean way of life.
Tenochtitlan was one of the most populated cities in the world when the Spanish arrived
