Is "lose" more important than "win?"

In a dictionary of mine there are a lot of descriptions about the word "lose," which occupies 217 square centimeters of space. The word "win" occupies only 85 square centimeters.

lose confidence/interest/hope etc
lose heart
lose your temper/cool/rag
lose your head
lose your mind
lose yourself in something
lose something in the translation/telling
. . .

Have I lost myself in reading dictionaries?
