And as a fellow Greek man said, "Just because you do not take an interest in politics, it does not mean politics won't take an interest in you".
My interpretation of the statement is that you can't ignore forces that affect you, even if they bore you. However loudly or frequently you declare or think "I don't care for gravity" matters not as it exists outside of your awareness or acknowledgement of it.
Taking parent's cue of assuming lack of agency - you can even replace "politics" with "the weather", and gp's comment still makes sense, parents inverted riposte does not make sense under its own priors. We can't change the weather, but it's prudent to know which days to carry an umbrella.
