I recently purchased a used MacBook Pro 2019 A1989 and I’m curious how good the battery life is with these descriptors. He said it’s 634 cycles out of 2000? I’m confused. I’m looking for a general percentage;
Fully Charged Capacity (mAh): 4325
State of Charge (%) : 100
Cycle Count: 635
Condition: Normal
MacBook Pro (2017 – 2020)

When new, that Mac came with a 5086 mAh battery, so it has 85% of its original capacity. The battery is considered to require replacement when it reaches 80%, so it is roughly 3/4 used up. Also, the batteries are rated for about 1000 cycles (not 2000), but the capacity shown is a better measure of how much longer that battery might last. If you have the latest MacOS and have Battery Health Management active, that will maximize its remaining life. All batteries are consumables and have to be replaced eventually. The battery replacement can be done in an Apple Authorized Service Provider shop.

Determining battery health is complicated since there is a lot more to battery condition than macOS is able to report. You may want to try the third party app Coconut Battery which will at least tell you the Full Charge Capacity (FCC) in relation to the original Design Capacity. It will also keep a bit of FCC history which may show you that FCC may be fluctuating....perhaps going lower than you realize.
The only thing the Cycle Count tells us is the battery is well used with maybe about 36% life left assuming there are no hardware issues with the battery.
I usually tell people to not worry about the battery condition & values. Just use the laptop normally until the battery no longer performs to your expectations, then check these values to see if the battery condition shows as "Service Recommended".
Good catch on the FCC! For some reason my brain was telling me the OP had posted the Design Capacity since that is all macOS normally provides to the user of an Intel Mac.
