Hearing that a recession is a good time to make a lot of money... what do i do?

Hello, sorry if I sound like an idiot but I don't want to make any mistakes. I am 18 and I have around 10k+ lying around; I make around 200 dollars every weekday cause of a little side hustle but that won't last long. I keep seeing posts and videos that for people with money available for investing, a recession is a golden opportunity to get rich. I need to take care of my mother, and the 10,000 I have is not enough for that.

Can someone guide me to where I can learn about what is going on and what I can do to take advantage of this recession? I imagine there will not be many opportunities in my life where I can use 10k of disposable money lying around for investments, and right now it is very important that I can get enough money to take care of everything.

Thanks
