Short answer: a wallet is an app or device that holds the keys to your crypto, not the crypto itself (that lives on the blockchain). The seed phrase - 12 or 24 words - is your money. Anyone who has it has the funds. Never share it, never type it into a website. General information, not financial advice.
“Wallet” is a slightly misleading word. Your coins never leave the blockchain; the wallet just stores the cryptographic keys that prove the coins are yours and let you spend them. Understand that and the rest is straightforward.
A common setup: a hot wallet with a small spending balance for payments, a cold wallet for savings.
The one rule: your seed phrase restores the entire wallet. No legitimate person, support agent, app, or website will ever ask for it. Write it on paper, store it offline in more than one place, and never photograph it or paste it into anything. If a site asks for your seed phrase, it is a scam - leave.

What is a seed phrase?
12–24 words that restore your wallet and all funds. Whoever has it controls the money. Keep it offline; never share it.
Hot vs cold wallet?
Hot = online software (spending). Cold = offline device (savings).
Custodial vs self-custody?
Custodial = a company holds your keys. Self-custody = you hold the seed phrase and full responsibility.
