A: euphemism
B: paradox
The text uses a paradox, a statement that might at first appear to be contradictory, but that may in fact contain some truth.
Never say never at first appears to be contradictory: by saying the phrase itself, you have already said never. However, it contains some truth: people often change their minds as they age and so should not rule anything out by saying never.
