I play guitar, but some people say that playing the piano is easier to pick up girls than playing the guitar. Is this true?

False.

The guitar can be played at any time, but the piano can only be played at certain times. For example, I have a level 10 piano, but I rarely have the opportunity to perform. Except for the welcome party when I was a freshman, I participated in a program, which was basically nothing. Suitable for performance occasions.

The guitar is different. You can take it with you to play at any time, on the playground, in the classroom, and on many occasions. Moreover, the guitar accompaniment is more effective.

Piano accompaniment is very technical.
