I have an M1 macbook 13 inch. How long is my battery typically supposed to last before needing service
user
The user manual says that “A fully charged battery should provide approximately seven hours of use at normal power levels. The battery’s charge will decrease over time” (link).  In fact, though, battery life varies quite a bit based on your usage patterns.

I use my laptop daily.

That seems to be a pretty good average usage pattern, so a fully-charged battery should last more than seven hours.

I'm not asking about how long my battery lasts on a charge, I'm asking about the lifecycle of my battery

Sorry, I think the question was about the overall lifetime of the battery, right?  I wasn’t sure you were asking about the time until the battery was fully drained, so I explained what the user manual says.  The lifetime of the battery is also going to depend on how much you use the laptop.  Let’s say you charge your battery with a plug, and it’s fully charged, and then you unplug it, and use it daily.  I think we’re looking at something like a 10 year life for this battery, but I’d need to do some further research.  For this

A laptop battery, the device that makes your laptop portable, is essentially a chemical storage tank.  When you remove power, you’re turning off the chemical storage, and the battery will deplete over time.   I don’t know of a source that gives an estimate of how long your battery will last after the first charge.
