As the title states really, I need to know if a 32bit application can access a 64bit sql server database?

To work around this problem, use the appropriate version of the ODBC Administrator tool. If you build and then run an application as a 32-bit application on a 64-bit operating system, you must create the ODBC data source by using the ODBC Administrator tool in %windir%\SysWOW64\odbcad32 .exe.
And in 2022, SSMS is still 32 bit.
Key Difference Between 32-bit and 64-bit32-bit processors have 4 GB addressable space while 64-bit processors have 16 exabytes addressable space. 32-bit processors need a 32-bit operating system whereas 64-bit processors can run either on 32 or 64 64-bit operating systems.
Yes
An application won't care if the target database server is 32 or 64 bit, Windows/Unix, Server/Mainframe, local or in the cloud. All it knows is the connection string it sends to a driver on the local OS.
To be clear, the local OS and driver don't care about 32 or 64 bit on the target system

Yes they can and usually there is no problem.
Some large datasets might cause an issue but you would need a record with over 3gb of data...
