You say "the people" are the citizens. Very close. But Article I, Section 2 of the U.S. Constitution says that "the people" vote. In 1792, that would have eliminated women and children, since they weren't alowed to vote.
So, what does that leave us with? Adult, white, male citizens. They had the right to keep and bear arms. Just them. That's all.
That was less than 20% of the population at the time. If the second amendment protected guns for other reasons (like self defense and hunting), over 80% of the population didn't have the right protected for them.
Close, it was slightly larger than 20%.
According to the 1790 Census, it was 807,312 free white adult males out of a total of 3,893,874.
By the way, that is group is about 300,000 larger than the figure we discussed for the militia.

Yes they did because it was for all citizens not just white males 18 to 45.
