Not clear about camera spec video modes example 3840 x 2160 @ 30p / 100 Mbps

I am not understanding in camera spec :

Panasoinc GH5 :
1920 x 1080 @ 60p / 200 Mbps, MOV, H.264, Linear PCM

Sony A6500 :
1920 x 1080 @ 120p / 100 Mbps, XAVC S, MP4, H.264, Linear PCM

1920 x 1080 @ 60i / 24 Mbps, AVCHD, MTS, H.264, Dolby Digital

.

Now my doubt is :

first: 1920 x 1080 is telling per frame resolution
Second: @ 120p is telling that in one second 120 frames are recorded
third: 100 Mbps is telling that 100 Mbps amount of data will be recorded per second

Does this mean if 100 Mbps / 120p = 0.833 Mega Bit amount of data having for one frame (that is very small size, so inferior video quality)

So which means if the data transfer rate is higher each frame will get more data to capture and better quality of the video. example GH5 have 200 Mbps on 60p for 1920 x 1080 resolution will gives 200 Mbps / 60p = 3.33 Megabit for each frame.

Or I am completely misunderstanding everything?

Note: I know both GH5 and a6500 have different size of the sensor which may influence the quality of each frame of the video but If we are assuming both GH5 and a6500 have exactly same sensor then does the high Mbps denotes the better quality of each frame in the video. ?

Another thing why spec mention 60p and 60i (interlaced and progressive scan) does this means that with interlaced (60i) during recording each frame will include half of the image by stripping lines discreetly throughout each frame. ?

ANSWER:
Panasonic GH5 Sony a6500
