Is Avalanche fully decentralized?

I've been hearing a lot about Avalanche recently, and I'm curious about its decentralization aspect. Could you elaborate on whether Avalanche is fully decentralized? I've read that it supports multiple validators and each validator stakes a certain amount of AVAX tokens, which sounds promising for decentralization. But I'm still unclear about whether this is enough to guarantee complete decentralization. Is Avalanche truly free from any centralized control? And how does its consensus mechanism contribute to its decentralization efforts? I'm eager to understand these details as it's crucial for assessing the overall security and reliability of the platform.
