I am totally new to Blender, but I noticed that software uses some libraries from the FFmpeg project (libavcodec, libavdevice, libavformat, etc.). Also, Wikipedia says Blender uses FFmpeg. Blender itself says ("Output Properties") the "File Format" in the Video Sequence Editing (VSE) is "FFmpeg Video".

As a preamble/aside, I've found the Blender forums to be a helpful resource (https://blenderartists.org/). If you have a sustained interest in technical details there's a development/technical forum as well.

So,

#1: is Blender a kind of frontend of FFmpeg?

Blender can use ffmpeg to write nedia files. It looks like avformat libs are also used for importing (some?) media, but I haven't had more than a trivial glance at the code. This doesn't mean that Blender is simply a frontend for ffmpeg in the way Kdenlive and co are frontends for the MELT framework, however.

#2: Can all Blender's operations on video be achieved by FFmpeg?

What operations on video in particular do you mean? If you mean everything you can do in the VSE (video sequence editor) then the answer is that you can probably, by dint of effort, achieve many of the same outcomes via ffmpeg that you can with Blender and possibly more- but the obvious question arises: why? Trying to manage a long complex filtergraph with many filters/operations "by hand" in ffmpeg is non-trivial. Cheers, Rob
