What do you think when a friend or partner does something wrong and instead of apologizing for it they say 'im not perfect'?

They offer no apologies and anytime you point something out to them this is their go to thing to say.

It makes me think they will just do or say it again in the future
They don't take accountability for their actions/words
They lack the ability to self reflect
It's just a cop out
it's redundant to say like 'yes we all know that human beings aren't perfect, duh!'
I don't see the issue with that instead of apologizing actually
I'd think something else (what would you think?)
