I recently purchased some used RAM from a marketplace, and the seller just wrapped it in plastic. I've placed the RAM in ESD film for protection, but I'm still concerned that it might be defective. I'm currently unable to build my PC since I'm missing a few parts, and I'm worried about the risk of the RAM damaging other components like the motherboard or CPU if it turns out to be faulty. How likely is this risk, and is there a way to test if the RAM is functioning properly?

I've sold and bought tons of used RAM, and I've never seen it packaged in an ESD bag either, so I wouldn't worry about wrapping it in plastic. It’s not a common practice.
It's highly unlikely that the RAM is going to damage any other components. Defective RAM typically won't fry other parts, so you can rest easy on that front.
There's very low risk of the RAM damaging anything else. To check if it works, just install it in a compatible motherboard with a CPU (make sure to include integrated graphics or a GPU) and run a test using Memtest86 from a USB stick overnight.
