The only stats I can find are https://www.idealista.com/news/finanzas/economia/2023/03/03/... - that shows 30k people actually evicted from houses they were renting but stopped paying for in 2022.

Can't find any numbers on how many people are not paying and indefinitely staying in flats. While I'm sure it's a slow process, personally I'd be surprised if there's that many people in that situation long-term, since there's clearly laws and a working process to remove tenants in this case (30k evictions for non-payment in a year means forcing an eviction is clearly possible).

Idealista has some details on the process and how long it takes here: https://www.idealista.com/news/inmobiliario/vivienda/2022/10... and suggests that 7-8 months is typical (really interesting how effectively Idealista dominates as the source for info on all these topics, superb example of content marketing).
