Mod "level" means how many times you upgraded it. All mods drop as level zero, except fusion cores. Where the article says "levels ranging from 0 to as high as 10 (typically 3-5)" means that some mods can be upgraded ten times while most can only be upgraded three or five. This is shown by the notches on the left side of the mod card.
