Does Katniss’s use of the word survive in the final para of mockingjay suggest Gale was right?

To me it depends what context Gale meant when he said survival. If he meant it physically then he is wrong but if he meant it emotionally, then I think what he said makes sense.

Katniss needs the gentless and hope Peeta gives her and that is the conclusion she reaches at the end of book. Her use of survive at the end is used in that context. Gale wouldn't be able to give her that and it is Peeta she developed romantic feelings for in the end
