There are a whole bunch of assumptions here. But sure, if you view the world as a closed system, then you have a decision as a function of inputs:

1. The world around you 2. The experiences within your (really, the past view of the world around you) 3. Innateness of you (sure, this could be 2 but I think it's also something else) 4. The experience you find + the way you change yourself to impact (1), (2), and (3)

If you think of intelligence as all of these, then you're making the assumption that all that's required for (2), (3), and (4) is "agentic systems", which I think skips a few steps (as the author of an agent framework myself...). All this is to say that "what makes intelligence" is largely unsolved, and nobody really knows, because we actually don't understand this ourselves.
