The moment you said "subjective analysis" already invalidated the rest of your argument and supported what I said -- you are just saying it's okay to use you a set standards that are not universally accepted to judge others. It's probably not your intention to come across that way, but it is exactly this type of thinking that brews toxicity.
The OP of that "wannabe" comment could have finished the sentence without saying anything about wannabes and still get the same point across. So why bother calling everyone else who can't get their games paid wannabes?
Do we have any evidence that these wannabes are not "some people just want to make great games, don't care about getting famous"? What's wrong with wanting to become famous as a goal in the first place? Who decides who has the chops and who doesn't?
You simply can't unless you are objectively the best at something. The complexity in deciding what is objectively the best makes such efforts futile, and therefore everyone who thinks it's okay to call others wannabes is just conveniently glossing over the fact that they are also wannabes by someone else's standard.
