I assume you haven't read the books. Gollum's ring is the One Ring, forged by Sauron to enslave all of Middle-earth. It is a thing of great evil power. The Dark Lord made it along with the nine rings given to the Men, three to the Elves, and the seven for the dwarfs. Sauron made his to control them all. An example of this dark power is the conversion of the nine kings of Man into the nine Ringwraiths.
The Ring gives long life to its bearer, like it did to Bilbo, and it makes the person invisible when they put it on. But that turns them little by little into a creature of darkness.
I hope this helped! And if you haven't done so already, read the books! :)
He is Smeagol's (gollum's) cousin.
In "The Hobbit," Bilbo learns from Gollum's mutterings that the ring he possesses has powerful and dangerous properties. Gollum's references to the ring reveal that it can make its wearer invisible and is deeply tied to his own identity and obsession. This encounter helps Bilbo understand that the ring is not just an ordinary object but something that could have significant implications for his journey and future. It also foreshadows the ring's greater importance in the larger narrative of Middle-earth.
Bilbo asks Gollum "What's in my pocket" (the Ring) and Gollum cannot answer.
Gollum
I believe Gollum was wearing The Ring, using it to catch a stray goblin off its guard for something other than fish to eat and The Ring slipped off his finger without him realizing it. In Gollum's own words, "How did we lose it, my precious? Yes, that's it. When we came this way last, when we twisted that nassty young squeaker. That's it. Curse it! It slipped from us, after all these ages and ages! It's gone, gollum." It is a magical ring, remember, with almost a mind of its own.
Gollum takes the Ring from Frodo by biting off the finger bearing the Ring.

Gollum guesses that Bilbo has found his magic ring.
His precious
It was the One Ring. His cousin Deagol found it in the bottom of the river Anduin and Smeagol (Gollum) killed him for it. One of the justifications was that it was his birthday and it was a present for him. The Ring is important because it is the pivotal reason for the entire book: the re-emergence and ultimate destruction of the Ring.The way that Gollum came by the Ring is also important: because the Ring came to him by evil means, it corrupted Gollum that much easier. In the end, Gollum's complete corruption and lust for the Ring was what (ironically) saved Middle-Earth.
Gollum is a Close relative to the hobbits who gets changed by the influence of the ring.
Bilbo said, talking to himself, "what have i got in my pocket?" (it was the Ring). Gollum thought it was a riddle and Bilbo decided to make it one. he gave Gollum three chances to guess and gollum lost after four. then gollum went "to get something" (it was the ring), and Bilbo thought he was abandoned and left with the ring on. Gollum thought Bilbo knew the way out and he wanted to follow him, realizing Bilbo had the ring. Bilbo saw Gollum racing towards the gate and followed him to safety.

Bilbo escaped from the cave in The Hobbit by using his wits and the magical ring he found earlier in the story. He put on the ring, rendering himself invisible, and slipped past Gollum, the creature guarding the exit. Bilbo then followed Gollum out of the cave and made his way back to the company of dwarves.
