why it’s possible to scroll through your screen with your finger tips but when you wrap it (your fingertip) with, say, a very thin cloth, the sensitivity reduces greatly

Your phone screen detects an electric charge in your fingers, which is why if you tried using a pencil to scroll it wouldn’t work unless it was a stylus that was compatible. I would say that a cloth(like wearing gloves) disrupts that electric charge path from your finger to the screen. therefore it won’t let you scroll at all or the sensitivity is reduced greatly.
The screen (most of them, at least) work by detecting minute changes in the flow of electricity on the screen. You need to press the screen with something conductive (say, a finger) for the screen to detect a chance in resistance, and even thin gloves are enough to interfere with that.
Some screens work by layering two membranes on top of each other and detecting where they are pressed together which doesn’t care at all about what you press it with, but those are also more prone to wearing down due to the moving parts.
