Is Ledger 100% safe?

Could you please clarify, is Ledger completely devoid of any risk? Is it absolutely assured that my cryptocurrencies are fully protected when stored on a Ledger device? Given the volatile nature of the crypto market and the ever-present threat of hackers, I'm seeking reassurance that Ledger offers uncompromising security. Is there any potential vulnerability that I should be aware of? Or can I confidently rely on Ledger as a secure vault for my digital assets? Your insight into this matter would be greatly appreciated.
