Does the Catholic Church teach that only its members are saved?
The answer is a bit complicated, and depends on what you mean by "member" and "Catholic." But it's safe to say three things:
1) Being called a "Catholic" on earth is NOT a one-way ticket to heaven.
2) Being non-Catholic is NOT a one-way ticket to hell.
3) A person can be a member of God's Church without even knowing it.
