In plain English
What Seed phrase means
Many wallets show a set of words when the wallet is first created. Those words are meant to be written down and kept secure, because they can restore access if the device is lost. In many systems, the phrase is a human-readable form of the secret material that generates wallet keys.
Why it matters
The seed phrase is often the only recovery method for self-custody wallets. If it is lost, access may be lost permanently; if it is stolen, someone else may be able to restore the wallet and move the funds.
Example
A user buys a hardware wallet and writes down the 12-word recovery phrase on paper. Months later, the device fails, but the user restores the wallet on a replacement device using the same phrase.

Not necessarily. It depends on the wallet standard and derivation path used by that wallet.
