what gauge is the wire?

Seller is misinformed or lying - it's nowhere near 20 gauge. Maybe 24 or 26.

Will this work with the ws2812b 5mm width led strips?

It should. It lists ws2812B in the title and narrative. Hope this helps.

How do you connect jst sm 3 pin connectors to the arduino uno board and power the led's?

These connectors are for the WS2812B or neopixels, they are individually addressable so if they are in a strip you can control the color and intensity of each led. They have a positive, negative and a data connection. For more detailed information go to adafruit.com, they have wiring diagrams and sample code.

Is this just the connectors or is the ribbon cable attached to the connectors?

The ribbon cable is attached to the connector.
