This is indicative funding, it's what can be spent, not what is actually being spent. It's 93.5 billion € over 6 years, only 5% spent so far, the UK spends more that it gets, but not by as much as you say.
Yes, and if horizon Europe was solely about gaining funding then it would be a dud deal but there are a lot of other advantages brought by the program that benefit the UK, either through indirect financial returns, like access to markets, and non financial returns like steering development to address issues more pertinent to UK environment.
If everything was just about money then it would be really easy calculate the ROI upfront and then decided to opt out.

The UK is on that list because it's an associate member of Horizon Europe and contributes €2.4 billion annually into it.
