I bought a MacBook Air M1 in April'21. It's been 2 months and close to 30-35 complete battery recharge cycles. I'm not sure if this is normal, but after 2 months of usage the maximum battery capacity has gone down to 98%. Could someone please clarify.
MacBook Air 13″, macOS 11.4
If you use it as a mobile notebook, there is a chance that battery cycles can add up.

How battery health management helps
The battery health management feature in macOS 10.15.5 is designed to improve your battery's lifespan by reducing the rate at which it chemically ages. The feature does this by monitoring your battery's temperature history and its charging patterns.
Based on the measurements that it collects, battery health management may reduce your battery's maximum charge when in this mode. This happens as needed to ensure that your battery charges to a level that's optimized for your usage—reducing wear on the battery, and slowing its chemical aging. Battery health management also uses the measurements to calculate when your battery needs service.

Batteries are considered Consumable Products. Over time it will degrade to a point where it needs to be replaced. In you case - the usage is normal as the capacity will go up and down all the time and never stay always at 100%. Apple Batteries are rated for 1000 Full Battery Cycles and / or 80% Capacity before needing Evaluation or replacement.
