English has these words that your language does not, because it borrowed heavily from several other languages in the past. Having only one language would kill off that source for diversity.

Dutch also has one word for happiness and luck ("geluk"), although in Flanders you can use "chance" to express "luck" specifically (borrowed from French).

In some ways, English allows for more specificity compared to German, but the reverse is also true.
