If it's a credit card then you should have pretty decent protection against fraud from the credit card company. I've had my card details stolen a few times (though never directly from my browser) and each time the credit card company has identified the fraud and reached out to me within minutes.
Now if it's a debit card, you should NEVER put those numbers into a computer. I only ever use my debit card to access the ATM, and even that is rare.
Sounds like a very US specific answer. In EU I only have a debit card and sometimes I have a hard time using it even myself because I need to pass 2fa and sometimes even that isn't enough if I'm on a new browser
Credit cards work the same everywhere*, it's not US-specific. My debit card actually only has my bank account number on it (but I think that actually is a Germany-only thing with our Girocards), so paying for stuff online is just a normal bank transfer, where yeah you do have to pass the bank's 2FA (unless it's via SEPA direct debit).
* mostly, my card requires me to confirm some charges in a special phone app, I don't think that's a thing everywhere since it's also fairly recent
This is on account of the concept of SCA (Strong Customer Authentication) from PSD2 (Payment Services Directive), an EU-regulation.
