Anecdotally, I definitely am thinking first and later applying words to the underlying concept. It takes practice, but it is possible to introduce a lag, of sorts.
Further, the best hunters, I’ve heard, are the most empathic. All the better to manipulate prey.
Even more, my cat is very expressive despite not having English. I can even identify patterns in his speech that clearly repeat for similar reasons. I spook him, there’s a meow for that. He’s hungry, there’s a meow for that. He’s tried and I’ve ignored 2 attempts of his to ask me for something and he’s pathetically resigned to his fate, there’s a meow for that. (Gets me every time)
You can also think without words. You do that any time you visualize something. Imagine an apple floating in an empty black space. Just reading these words probably put that image in your head. Now turn the apple around, look at it from all sides, above and below. I can definitely give you directions on what to do, but I have no idea how to think that visualization in words.
This isn't what I meant, or what is generally meant, by language.
Humans are distinguished by our ability to generate and understand novel sentences. This isn't a question of scale -- it's not a question of the number of things we have names for. It's a question of the ability to create and understand sentences that have never been created before. No other animal does this, as far as we know.

I'm not sure I can visualize something without naming it or describing it.
Say you're playing basketball. You're thinking in terms of the ball, the net, the other players, and so on, not thinking in terms of a language.
I can imagine that (for example) a bird building its nest finds itself in a similar situation. It's thinking in terms of the nest -- what shaped sticks to gather and where to place them -- even though it doesn't have any capacity for language.
Perhaps animals think without language and experience a state that could be termed consciousness despite not having language. Sure, why not? But my point is that there is at least some grounds for this "high-horse proposition" because there is at least one important dimension along which humans differ from all other known animals.
