Hardcore poker players use profiling softwares to choose which table to play. Profiling softwares helps them to find tables where a majority of the players are weak and the software also gives them all the information regarding your play. If you ever feel like they already know what you are going to do next, you are probably right.

The main difference between empirical poker calculators and profiling softwares is that if you use an empirical calculator you have to play against an opponent to get a profile of his poker playing style. In profiling softwares all of this data is already collected and you can access it at once.

If you use a profiling software, like poker edge, you will get the upper hand because in poker information is everything. If this information is used correctly that player will be very hard to beat.
