You enter a term, and depending on what you entered, you get a very different UI.
"best sled for toddler" -> search modifiers (wood, under $20, toboggan, etc.), search options, pictures of sleds for sale from different retailers, related products, and reviews.
"what's a toboggan" -> AI overview, Wikipedia summary, People Also Ask section, and a block of short videos on toboggans.
"directions to mt. trashmore" -> customized map of my current location to Mt. Trashmore (my local sledding hill)
Google has spent an immense amount of time and effort identifying the underlying intent behind all kinds of different searches and shows very different "UI" for each in a way makes a very fluid kind of sense to users.
