If the information is wrong, you can easily correct this via your account on openstreetmap.org (as of one example on how to do this, also the best solution for lazy people). After you've saved the changes, the correct information will be searchable basically instantly.
I update through streetcomplete, and I generally don't see information updated soon. However
how do I do this on web? For e.g. if I search golden gate and it's not correct result, I may not know exact coordinates/address of the poi.
How do I work with map if i'm working with unknown (to me) poi?
There are a variety of geocoders that use OpenStreetMap data.
https://wiki.openstreetmap.org/wiki/Geocoding
Availability of address data varies by area.
but these are used by services right? (not full service itself). Am I misunderstanding?
Qwant maps seem to work well
