In LNURL-pay in general, the URL (encoded with bech32 encoding in QR code) can be anything, for example https://server.com/anythinghere.
In Lightning Address (subset of LNURL-pay), final URL is ALWAYS ".../.well-known/lnurlp/<username>".
My god... Encryption - converting plaintext to ciphertext
Small correction from my side - "...which is encrypted using bech32 encoding".
Encryption - converting text to text using a secret key. No one who does not know this secret key can decrypt the message.
Encoding - converting one form of text to another but without any key. It's just another representation of the same data and everybody can encode/decode.
bech32 is not encryption, it's encoding. Sorry for that.
