Estimates are indicative. Real output depends on exporter, JPEG quality and how compressible your textures are. Draco shrinks geometry, not textures.

Pro Tips
Textures are the budget. One 4K map can outweigh a 100k-tri mesh. Drop resolution before decimating geometry.
KTX2 for web. Basis-compressed textures cut download and use less GPU memory than JPEG or PNG.
Atlas your maps. Fewer, packed textures beat many small ones for both size and draw calls.
