As a long time theatre professional, all theatre is non professional. Or rather, it's not a business, and therefore there's not an avenue to success.
All theatre, even (and especially) Broadway exists only because rich people funnel free money into it. Regionally as donors, and on Broadway as "investors" who almost never make a return.
It is a rich people's hobby and for those who do make a career out of it, it's lottery winning odds to be middling comfortable. One percent of one percent become well off.
You may also notice, as an audience member, that it is almost universally terrible entertainment. It just sort of shuffles on through the centuries with an occasional Hamilton and lots and lots of wealthy networking opportunities.
