I like your interpretation, and GP could be rewritten to mean that.
As it stands now:
GP responded to someone with presumably bad parents by reminding them that their parents contributed to their existence. This sets the stage for their followup advice.
Their followup statement about unconditional gratitude is either directed at this person or uses a universal 'you'. This advice cannot be applied universally, especially in cases of abuse.
The final sentence also implies that GP has found something universal: "It also takes some people way too long to realize this".
---
A lot of people say to themselves - "Of course there are exceptions!" A person's understanding of what counts as an exception is based entirely on their personal experience. Humans also tend to presume that other humans are "normal" unless given evidence otherwise: evidence also based on their personal experience.
We don't know the history of the majority of the people we meet, nor are we entitled to it. How do you determine who is an exception and who is not? It isn't feasible. GP's final sentence implies that it is.
All of these things underpin GP's comment - it's a common pattern of thinking.
