I advise to stay away from Ledger hardware wallets, too. Their firmware is closed-source and nobody except Ledger knows what this firmware can do and what actions can be triggered by any software able to communicate with a Ledger hardware wallet.
Ledger Live is known to be crappy here and there and I don't expect this piece of software shit to be designed with security as top priority.
Ledger offers a subscription service that extracts your wallet's secrets and shares it with affiliated companies to offer a convenient and expensive wallet backup service. With that they lie about one of their early marketing key points that your wallet's secrets can't be extracted from the hardware device.
And Ledger uses cheap and crappy hardware components, with lots of screen and battery issues reported. Enough of ranting about Ledger crap. I would've chosen a Trezor Safe 3 as a replacement or any other decent open-source firmware hardware wallet.
When you setup a hardware wallet, you should backup your mnemonic recovery words and other details of your wallet AND practice a full recovery from scratch, otherwise you rely on hope to be able to recover your wallet and not on the proven fact of it.
For practice and to play and explore your new device's capabilities you can use Testnet bitcoins which should be available for free.
As others have said already, your coins are not stored in your hardware wallet, only the private keys are secured there which enable you to move your coins on the blockchain where they "live".
