And also, in addition to what Zachy said, 1 cycle count is equal to the drain on a battery, not necessarily on how many times you have charged it. For example, if your battery drained 25% a day and you charged it for 4 nights, that is only 1 cycle count.
Another thing to consider is that since you said you have charged your iPhone 15 Pro only 3-4 times, that indicates you may have purchased a refurbished phone or from a third party. Unless the refurbished phone was purchased from Apple, you don't know if the battery is genuine or the information provided in the Battery stats is even accurate.
Recalibration of battery health only happens when you charge your iPhone to 100%. Thats the same reason why when you have a Charge Limit enabled, it will still occasionally charge to 100% to calibrate. If you are preventing that it won't do so.
