Is there a risk in staking ETH in ETH 2?

I staked almost 2 ETH many many months ago and recommended it to my girlfriend as it feels like a no brainer if you believe in the technology long term.

However, when she went to stake (Coinbase) there was a disclaimer that she could potentially lose all of her ETH, not just her staked earnings.

I didn't remember that disclaimer so I went to stake more and I didn't get the disclaimer…? Is there no risk to me and just new stakers? Am I also at risk for losing all my ETH I have staked? I read quite a bit about staking and doing remember anything about potential losing my ETH.

Can anyone shed some light on this for me??
