They don't claim e2e encryption by default, they just use some very tricky words that non-technical users will assume as encryption.

From telegram.org:

"Private: Telegram messages are heavily encrypted and can self-destruct."

"Secure: Telegram keeps your messages safe from hacker attacks."

"Encrypt personal and business secrets."
