create user someusername identified by somepassword;
grant create session to someusername;

Now if you want the user to be able to create objects in their own schema:
grant resource to someusername;

Note:  Any user will have access to ANYTHING that has been granted to the PUBLIC role.

So if access to SYS and SYSTEM objects were granted to PUBLIC, then there really isn't a way to keep users out.

Should also add the following if they are going to be creating objects:
create user someusername identified by somepassword
    default tablespace some_table_space_name temporary tablespace your_temp_tablespace_name;

This sets up the tablespaces they use by default.

I have in my database 100 users.
I want to create a 101th user which cannot access to sys and system.

OK, just run the create user statement for the 101st user.

I gave it to you already.

If you don't grant access to SYS and SYSTEM for any user you create, they don't have access.

With the one exception I noted:  ALL users have access to ANYTHING that has been granted to the PUBLIC role.

You cannot restrict a user from seeing PUBLIC items.  You need to revoke access for those objects from PUBLIC but that is a different question.

There are likely to be outliers on this, but as a general rule, Oracle user accounts CANNOT access objects (tables for this discussion) that belong to SYS, SYSTEM, or any other schema in the database.

The exceptions are as above.
1.  The object's owner has granted an OBJECT PRIVILEGE to PUBLIC.
2.  The object's owner has granted an OBJECT PRIVILEGE to the new user.
3.  A privileged user (DBA) has granted a SYSTEM PRIVILEGE to the new user or PUBLIC.

Examples:
1.  A user account may initially view information about objects it owns using SYS.USER_OBJECTS.
2.  A user account may initially view information about objects it owns, plus those to which a privilege has been granted, using SYS.ALL_OBJECTS.
3.  A user account may NOT view other SYS or SYSTEM objects unless it has been granted permission to do so (SELECT ANY TABLE).

I hope this helps, somehow....

Can you explain your selected answer here?

It appears you just picked the last post.  There is nothing in that post that shows you how to create a user which is the question you asked.

If you found in some of the information in that post helpful, you should award it some points but not ALL points.
