I think Minecraft changed the definition a little. Before Minecraft, a voxel was just a 3d pixel. Imagine drawing a single pixel using on paint, a voxel engine does that in a 3d space. A Minecraft voxel is much more complicated than a pixel in 3d. It has textures, the shape/graphics changes depending on what angle you see it from and can even have animations. I guess the term has evolved now but I find naming Minecraft as a voxel game mostly as a marketing gimmick. No one calls 8x8 block of a NES background tile a pixel
