00000001 is this enough SATs per coin longterm?

I am deep in Bitcoin and like everyone here I truly believe it's the future but I do have a serious question as I can't wrap my head around it. If there are 100 million SATs in one Bitcoin will it ever be affordable for everybody in the world to accumulate SATs as well as is there enough SATs for the population which is only getting bigger by the way. We all want Bitcoin to go to a million dollars, but what does that do across the board for people to have SATs to spend like currency one day? Don't hate, just a question like everyone else asks in this group.
