Yes, Bitcoin is not Ethereum, where they don't have checksums for addresses. Which bank account numbers have since 1960s (Luhn algorithm).
Ethereum does have checksums, they are just optional: https://cointelegraph.com/explained/ethereum-address-checksum-explained
Note that checksums are optional in bitcoin too, as sending directly to a pubkey is still a standard way to send money, at least at the protocol level; but it's not commonly supported by wallets, except in the case of taproot, where the common way to do that is to wrap it in a checksummed format anyway.

Indeed! Don't follow it too much, was introduced at some point, but wasn't supported initially.

You mean P2PK? Who uses that nowadays?

I'm not aware of any wallet that supports it except electrum, I think (I've never tested it). Taproot also uses a form of p2pk, though I'm not aware of any taproot-supporting wallet that lets you send to a "raw" pubkey; they all want it wrapped in the bc1p format, where there is a checksum.
