Correct, Exchange Server CUs and SUs are cumulative, you just need to install the latest CU and SU releases. Please mark it as best answer in case that answered your question
Appreciate eliekarkafy for prompt reply.

HI eliekarkaf, one more quick question, for Exchange 2019 CU 12 do i need to update schema as well manually
and what about Dotnet?

Yes its recommended to update the schema and update the .NET before installing the CU . When you run the CU it will check for all prerequisites in case your schema or your .net are not updates it will tell you to update them prior proceeding
