No. It was 1 GB:

https://en.wikipedia.org/wiki/History_of_Gmail

"after considering alternatives such as 100 MB, the company finally settled upon 1 GB of space, a figure that was preposterous compared to the 2 to 4 MB that was the standard at the time.[3]"

"On 1 April 2005, exactly one year after the initial release, Gmail increased the mailbox size to 2 GB, advertising it as 2GB plus"

The sample of the news from these times:

I referred to what Hotmail had at the time.

Yeah, the change to 100 or 200mb came as a desperate attempt later to stop the gmail hemorrhage.

I kind of remember that was something like 10 or 20MB, but yes, was about 2 order of magnitude less.
