Does it look like cloud storage or something?

Let me make it simple for you. So bitcoin blockchain is nothing but 277GB data containing records of every transaction ever happened on Bitcoin Network since its inception. Now your question is where is it stored, right? So the good news is that anyone can store Bitcoin's blockchain on any device he/she wants. To do so, person needs to run full node. As he does so, whole Bitcoin's blockchain will get downloaded on his system and he will be connected to Bitcoin Network and can independently verify transactions. I don't have exact numbers but last I remember is 47K nodes are presently running. So you can say up-to data blockchain data is present on 47K systems. It can be laptop, CPU, computers, Raspberry Pi, etc.

Decentralization is a key thing bitcoin brought to the world and changed it entirely.

Cloud storage is a centralized one but bitcoin is decentralized.

This is a very fundamental between cloud storage and bitcoin blockchain. You can lose your data that is stored on any cloud storage but you won't lose it if it is stored on bitcoin blockchain after 1 month. No one can delete such data on bitcoin blockchain.

Not exactly! Cloud Storage doesn't define centralization or decentralization. It is just a medium to store your data. Only difference is that you are storing your data on someone else's system. It is very much possible to run bitcoin node and store data on cloud. You can buy storage space on cloud services like 'Digital Ocean' and save blockchain there. It doesn't make any difference. Storing blockchain on cloud doesn't make it centralized as far as someone else is also having complete record on his system and can independently verify transactions.
