Col 1:20 Does the fact that Christ has reconciled all things to Himself through His atoning death mean that everyone will be saved in the end as some think?

No, salvation only applies to those in Christ.
All things here do not include those who do not believe in Christ, as scriptures clearly teach (CP V21-23 with Mk 16:16; Jn 3:16-18, 36; 5:24; 6:40, 47; 20:31; 1Jn 5:10).
Those who do not believe in Christ are doomed to eternal damnation.
The erroneous teaching that everyone will be saved in the end is called "universalism".
All things in Col 1:20 refers to all things in the created universe, not only humans; the whole universe of things, material as well as spiritual, will ultimately be restored to harmony with God (CP Ro 8:19-23 with 2Pe 3:10-13 and Rev 21:1).
