That isn’t usually how “cycles” works out, no, unless you deplete the battery completely every day.

I know from experience that a lot of people will recharge every day --- just to be sure.

How this will impact their definition of "cycle" is unknown but again; based on my experience with batteries, it won't be good.

I think you may be misunderstanding the meaning of "cycle".

Charging every night for a 5 day week, from 80% to 100% is 1 cycle (in this crude example).

A cycle is not the number of times you plug in a battery to charge, it's a single charge/discharge full to empty and vice versa.

There is more to it of course because you never really "empty" a lithium battery, and for longevity it may be configured to never be fully charged to 100%, but that's roughly the point.

Yes, most rechargeable batteries will degrade over time just sitting there --- without any "cycling".
