If we measured a year based on the rotation of the Earth around the Sun (solar year) instead of using the Gregorian calendar system, our birthdays would be on the same day each year. This would result in birthdays being the same distance apart with no variations due to leap years like in the current calendar system.

Yes, as everyone in the world has a birthday every year its around 3,999,999,999 birthdays. The exact number will never be known as people are born and die every day, and some rude people do not celebrate 'em. The number of birthdays on any particular day is about the same as the number of people in the world, divided by 365.
If you assum that people's birthdays are basically random and equally spread over the entire calendar, and each day out of the 365 in a year has the same number of birthdays for it, then just take the world's population and divide by 365. That's your answer for how many people share the same birthday. (P.S. that wont be exactly accurate because some months are known for higher births than other months).
In the United States, there are approximately 328 million people as of 2021. Each person celebrates their birthday once a year. Therefore, there are 328 million birthdays celebrated in the US each year.
