Is AVAX fully decentralized?

I've been hearing a lot about AVAX recently, and I'm really curious about its decentralization. Could you please clarify for me, is AVAX fully decentralized? I've read some conflicting information, and I'm not sure how to interpret it. If it is decentralized, could you explain how that works and what makes it different from other cryptocurrencies? On the other hand, if it's not fully decentralized, could you explain what aspects are centralized and how that might affect its overall functionality and trustworthiness? I'm really interested in understanding this better, so I appreciate your help in clarifying this for me.
