Bandwidth and frequency confusion
That is the open loop gain you are looking at.
It simply tells how much based on the open loop gain you can have closed loop gain at certain frequency before the amplifier hits a limit, after which it cannot provide closed loop gain due to the limit of open loop gain.
So yes, you can have a gain of 100 with frequencies ranging from 0 to 10kHz but you can't have gain of 100 at higher frequencies, and similarly, at 10kHz you can have gain up to 100 but not any more than 100.
