But you know, some people even said, not just focal length, but f stop is considered as f*1.6 for crop sensors.

It depends on what you mean by "considered as". If you want the same depth of field with FF and APS-C cameras, then yes, you need to use 1.6 times the F number on a full frame camera. FF cameras just require different settings to take the same picture. That's all they're saying.

(But it also means that APS-C sensors are slightly more limited. You probably cannot get quite as narrow a depth of field on APS-C as you can on FF. For example, you can easily get f/1.6 on FF, but you probably can't get f/1.0 on APS-C.  The converse is not true. You can get just as wide a depth of field on FF as on APS-C.)

Steve Balcombe's first reply was perfectly correct, well presented, and easily understood. I think that plus this reply are really all you need to know, although the other replies are also correct and add useful information.

Keep it simple and don't overthink it. There's a lot of confusing, misleading, and false information out there.
