So the answer to your question would be, in earlier CNN architectures as more and more layers were added to the Neural Network it was observed that the performance of the model started dropping, this was because of the vanishing gradient problem. Even though ResNet is much deeper than VGG16 and VGG19, the model size is actually substantially smaller due to the usage of global average pooling rather than fully-connected layers — this reduces the model size down to 102MB for ResNet50.
