Twitter dropshipping guys making claims of extreme success

There’s a circle of people on Twitter who claim they make a lot of money with dropshipping. Some claim around $1M per month revenue, some claim $300K per day revenue, some claim $500K per month revenue. To prove it, they show screenshots, videos of their cars and their lifestyle, etc. All of them are young guys in their early 20s. For example, I saw one 20 year old guy who claims he started a dropshipping store 4 months ago and has already scaled to $1M per month. They also claim a 20-25% margin. Some of these people sell courses. But some of them don’t. Some recommend the courses of others (without affiliate links). I’m confused whether to believe it or not. Is there any validity to these claims? Is it actually possible to scale a brand new e-commerce store to $1M per month in 4 months? Thanks!
