A matrix is a subset of a tensor and the 4x4 matrix is absolutely a tensor. Tensors can be way more complex and do more but the 4x4 matrix you use in 3D operations is a great starting point.

A matrix is an array of numbers. It usually represents a linear map (in some basis). A tensor is more like that linear map.
