In-game, no, apart from manually counting them, one by one.
Using external tools, sure. Simply ask a site like eddb.io for the total number of systems with stations - it currently returns the number "19,686". Now subtract the ones you'd consider to be "outside the bubble" - there's about 40 of them, but to get an exact number, click on the "distance from Sol" sort tab until it starts the list with the system furthest away from Sol. I'd call most of the systems in the list above Canopus "outside the bubble", but you're free to expand the bubble to include places like Maia and Sothis if you wish.
Anyhow,you'll probably get a number somewhere around 19,650.
This is inhabited stars, not uninhabited ones, or ones that the game considers "inhabited" but hasn't created any stations to land/dock at.
I'm not sure a 45 second minimum-duration jump-jump-jump qualifies as a "visit". But you should still have plenty of time, given the parameters.
Put it this way instead: visiting 19,050 systems in 31,536,000 seconds would give you just under 28 minutes per system. That should be enough time to arrive, scan the system if it needs scanning, set course for the nearest starport, fight off any pirates who might interdict you, land, do some trading, check the mission board, and take off again for the next system. Doing all that would definitely qualify as a "visit".
Or, if you prefer, you'd have to visit 19,050/365 = 52 systems per day. As an explorer I'm sure I routinely "visit" (arrive, honk , check system map, scan interesting things, jump to next system) that many systems per day, even when I'm just playing a few hours per day. So if exploration-style "visits" count, then "visiting" each inhabited system in the Bubble within a year should in theory be quite doable, even if you do insist on eating, sleeping and having a life outside of Elite.
As for the "richest CMDR", that's a statistic only FD can know. I suspect, whoever it is, that they've long since retired from active spacefaring and have settled down on their own private leisure planet by now.
...I brought up the question "I wonder how many humans inhabit the bubble"...
I guesstimated the total human population of known space to be around 5.9 trillion.
Interesting stuff!
Minor point - I don't think it's possible to do jump after jump at an average of 45 seconds...

Is there a list of or way to determine the number of stars/systems inside the bubble? Any creative way to figure that out?
