Ok so Mg 2+ has metallic bonding, but Mg20 has an ionic structure. Are metallic bonding and ionic structure basically the same thing?

Both lattices are held together via electrostatic forces, however magnesiums metallic bonding is held together via electrostatic attractions between the positive Mg2+ ions and the sea of delocalised electrons. Ionic bonding on the other hand is giant ionic lattices and they're held together via electrostatic forces of attraction between positive and negatively charged ions. They are similar, but not the same as in ionic lattices different elements are present whereas in metallic lattices, unless they're alloys like steel, it is usually just the metal.
Hope this helps

also im pretty sure Mg2O doesn't exist, would be Magnesium Oxide (MgO) or Magnesium Peroxide (MgO2)

No worries, good structure and bonding revision isn't it lol
