I think you're right, there must be some confusion here with the dates. These two coins are from 2024, commemorating the 150. anniversary of the Hungarian Chamber of Notaries (Magyar Polgári Közjegyzőség).
But in the 2025 plans of the Hungarian National Bank, there is a series for the 150. anniversary of the Hungarian Bar Association (Magyar Ügyvédi Kamara). I think someone might just confused these two institutions and updated the numista pages to 2025?

There is a chart on the page with some extra info:
3000 Ft, Cu-Ni, BU, mintage: 4000
15000 Ft, Ag, Proof, mintage: 4000
Interestingly, there is a pdf from the same page, with slightly different data: https://www.mnb.hu/letoltes/collector-coin-issuance-plan-2025.pdf
3000 Ft, Cu-Ni, BU, mintage: 5000
20000 Ft, Ag, Proof, mintage: 5000
Either way, these are yet to be released in late April. Also the designers are different of the 2024 coins and the 2025 ones.
