Yes, you're mistaken.

If you're the only person with the private key, you're the only person who can move the funds.

It's math. Unless you have a mathematical argument as to how to move funds without the private key, you're ignorant and uninformed.

If you’re depositing into a bank or exchange it’s not like 1 person is controlling that entire entities wallet(s). Deposits have the same risk of being misused in crypto as in fiat.

DEXs exist. What you are talking about has nothing to do with blockchains or self-custody.

Again, read primary sources and learn fundamental concepts before vaguely disagreeing.
