Maybe this was first-time lucky.

(Nora is thinking as well as dreaming)
Then she noticed in the top centre of the sign a little coat of arms around which orbited the words Oxfordshire County Council.
'We did it,' she whispered into the country air. 'We actually did it.'
This was the dream Dan had first mentioned to her while walking by the Seine in Paris, eating macarons they had bought on the Boulevard Saint-Michel.
A dream not of Paris but of rural England, Where they would live together.
A pub in the Oxfordshire countryside.
. . .
Maybe this was it. Maybe this was the life. Maybe this was first-time lucky, or second-time lucky.
She allowed herself an apprehensive smile.
(The Midnight Library by Matt Haig, episode The three Horseshoes)

I take "Maybe this was first-time lucky" to mean "Maybe this was the first time that Nora was lucky". Do I have this right?

"First time lucky" is a set phrase meaning that you succeeded by chance at the first attempt.
