Sort of, but the devil is in the details.
Disney pays property taxes, a ton of them. But they get do get breaks on taxes that are earmarked to cover certain essential services, like fire, ambulance, water, sewer, road maintenence, building code enforcement, and other stuff. So yes, there was a deal cut so that Disney has their own fire department, water treatment facility, emergency services, building code enforcement, etc. Disney was a planned development so they built all of that in to their infrastructure. They spend a ton of money for such services, and by all accounts, it is all run very well.
What this does is demand that Disney no longer run all of those things themselves. So the county will have to do it all, and the taxpayers will pay for the transition. Disney will pay more in taxes, sure, but this creates this huge bureauocracy where the former Disney employess are out of a job, presumably to become county employees, with lesser benefits, lesser pay, and probably providing lesser quality services.
It's shuffling of the deck chairs. The change will be messy, costly to taxpayers, Disney will by most analyses spend less not more, and for lesser services.
But it makes DeSantis look good to people who don't bother to understand what it is really about.
