About RandomResizedCrop(224)

Why we use random cropping for the image in deep learning, is it one of data augmentation? What if an important portion of the image is cropped?

Yes, it’s a data augmentation method.
Often your crop size is not much smaller than the original image size, e.g. you are cropping 224x224 patches out of a 256x256 image.
However, some techniques (IIRC in Inception) use larger differences between the crop size and original size.
