Yea, you can just win a bunch of matches.
If you want to unlock players fast, set the matches to 1of1 and easy in settings. Then, go to exhibition and pick whoever you want, then win 50 matches total. This is cumulative from the first time you ever played. You don't have to do it all at once.
When you hit 50 wins, you will have unlocked every player. Players seem to have the question marks in the achievments list.
Other achievements can usually be figured out by going to "Extras" in the table tennis main menu, then select unlockables/unlocked items/whatever and you can read what you have to do to get stuff. Many of the items have multiple ways, just highlight the items off and on and the description of how to unlock it will change.
Here's the list and what to do. Just felt like making you read a bunch
