Help understanding 10-K

Asalamu alaikum,

When I look at ISRG 10-K , it has a line item for “Interest and other income, net” and reports it as 3% of revenue.

So I am not sure if I am reading the 10-K correctly… does ISRG have revenue from interest? Zoya app says ISRG revenue is 100% compliant.

Also, if the interest line item says “net”, I understand that means interest revenue minus interest expense; so a company could have a substantial interest revenue but have more interest expense so they can report a loss under the interest category. I have seen this on some other 10-K. Is this correct?
