We are usually in situation that two processes requiring database access
work at the same time. Any of them can impose implicit lock updating
database. Does it mean that in such scenario we must use
sqlite3_busy_timeout() in front of each database access call to manage a
better way concurrent work?

Your programs cannot be reading and writing at exactly the
same instant in time. But both programs can have the database
open for reading and writing. While one program is writing,
the other is blocked from reading. But the write normally
only takes a few dozen milliseconds. Surely your reader can
wait that long.
The waiting is handled for you automatically if you set
sqlite3_busy_timeout()
