Disclaimer: I don't know much about 3rd world countries other than my recent trip to Africa and talking to some locals there. In short I've learned: access to healthcare is completely and utterly fucked (this is why maximum age seems to be 40 in the villages that I went to), getting food is a struggle but doable if you know what you're doing (you just plant stuff somewhere and hope it doesn't get robbed), you'll have a mud house somewhere, you'll be living close with your family, you'll be relying a lot on your community and your community relies on you.
My point of this entire comment is to say: be a bit careful with your words when you're from a 1st world country and the person you comment to lives in an entirely different context.
--- My actual comment ---
You seem to be based in the USA. This person is from a 3rd world country. Your advice looks like its written for an American, not someone who lives in a 3rd world country.
For example, I can imagine that a lot of people don't think that the world is a competitive place but a criminal one. Why? Because there are a lot of mercantile practices going on. Your passport matters. There is no meritocracy in this world, only passports.
Make the best of what you have in some cases can be translated to: try to fucking survive and I'm sorry that your relative passed away from malaria and that we had no money for medicine, and even if we did have money the infrastructure would be too broken to bring it fast enough. Sadly enough, that happens quite often. Technically, that's still the same as "make the best of what you have". But I can imagine that it can be perceived quite negatively, as some might see that there's some implied sarcasm there.
> This will make you more successful than your relative peer group
So instead of having an average age of 50, you'll get to be 60? More successful for sure. Yet, I can feel the unfairness to 1st worlders who get to be 80.
> It's a long game.
I don't think everyone perceives life to be a game. I know I do at times. But I also happen to know family members that almost die from hunger (rare thing to happen in The Netherlands but it does). I am sure that to them in those moments life is not a game. Because of that, I also believe that enough people who suffer from poverty or are threatened by it don't perceive life to be a game.

In closing: I think your comment was actually well meant. But since I see that you were downvoted I decided to take the time to explain how your comment seems to be missing the mark to me personally. I assume that other people have a similar enough interpretation of it.
FYI I didn't downvote, as I think your comment was well meant.
