I do not think that you are realizing that while some of the people made "fortunes" most of them lost their money back when it crashed, and a lot of people didn't even made any fortunes and they lost directly.
Some people enter at 10, reach to 200, and sell at 5 because it crashes, some people enter at 200 and sell at 80 because they are too late. Only the people who entered, and sold at the top made any money and they are not as common as you think, even the images you see people withdrawing, doesn't mean they profited, because they could have put that into another meme and lost it all. So do not be worried for staying out, I think you should keep staying out, it allows you to do something that's not that bad at all.
A great deal of what people can read on social media is either a bunch of lies or half-truths, the developers behind meme coins want to keep people investing in their useless projects with the hope of striking rich, and the way to do this is by creating the false impression there are many people making a fortune with their projects, but the number of people like that is very small, so I am sure they are pushing those numbers up by creating a bunch of bots which claim to have made a lot of money, and in this way attract more investors to their next projects.
