You could be right because there are so many dormant wallets that the owners might have lost access to due to forgotten passwords or seed phrases. There are so many things happening we might not understand especially seeing huge Bitcoin in a particular wallet without knowing that it was lost few years ago.
Even a lot of people think Satoshi himself probably lost access to his Bitcoin wallet. We haven't seen a single move of his Bitcoin wallet. If he had access to his wallet, or even if he were alive, he would have moved a single Bitcoin at least. But people think either Satoshi died or he lost access to his wallets. Or probably he sold a couple of his holdings, but we didn't notice.
There is a rumour that Satoshi mined 1 million Bitcoins. But do we know all the addresses belong to Satoshi? I don't think so. I personally saved most of my signature earnings and later spent it on my family. I am happy that I was able to become part of this forum.
That's baseless claims. Imagine the creator itself lose access of his Bitcoin wallet? He's not a nobody in the scene or a total newbie. For sure he have lots of experience for cryptography and know the consequences of losing the access of his own wallet.
He just vanish without a trace and those assumption is not valid since I believe Satoshi is genius and chances for that situation to happen is so less.
I just searched a topic about that mined Bitcoin before here it is

But if it happens that he really is I guess he deserve all the wealth he could get from Bitcoin since he is the one who create this coin.
