What does “risky” mean?

An address that passes syntax and MX checks but uses a disposable domain or role account (such as info@ or sales@). These checks do not guarantee mailbox delivery.

Does a valid result prove that the mailbox exists?

No. The tool checks syntax and the domain’s MX records, but it does not contact the mailbox or guarantee delivery.
