When asked to use a word in a sentence, a simple trick is to just define the word, which shows you both know how to use the word and also what it means. For example:
"A lottery is a means of raising money by selling numbered tickets and giving prizes to the holders of numbers drawn at random, or any process for which success is governed by chance rather than skill."
A poor example is "I won the lottery", as it does not clearly show you understand what a lottery actually is. That is, "I won the lottery" could imply the lottery is a race or some other form of competition that requires skill rather than luck.
You can use it as an adjective.Ex: I was full of joy when I won the lottery.

'I have apparently won the lottery.'
