I don't think that you're wrong in thinking that. That is how I view these systems. Artificial neurons and networks of them pale when compared to the complexity of any biological neural network. At a basic level, ANNs are a simplification of biological neurons but I think that we lose something crucial when we perform this simplification. So I think that there is deffinetly more to intelligence than what ML/Deep Learning is doing.
Freeman Dyson had an interesting lecture hypothesizing that at least part of why we haven’t been able to make anything like the human mind with our current computers is that our brains are analog.
