Does this mean its transparent to my ears?

Yes, this test meant that you cannot be sure or tell which file is the lossless one. When you are sure, you should expect hit 16 on 16 times, scoring 0.0% on the chances that you are guessing. (Here it said it was 96% chances you were guessing).

Thanks.I didn't understand the guessing part.

This page describes how to conduct a double-blind listening test and how to properly interpret the results. Among other things, it tells you how many "misses" you can have and still demonstrate that you're able to differentiate between the test sample and the lossless reference.

If you're purely guessing you seem to be somewhat unlucky since you're guessing right less than one third of the time. I'd expect to see something between 7/16 and 11/16.

Sometimes when I abx using foobar I just switch between x and y without going back to a and b and forget which was which and/or accidentally press the wrong button. Sometimes the differences are pretty slight and after spending too much time I've gotten fatigued and begin second guessing. I'm not trying to suggest that this is what's going on here rather what some of my personal experiences have been. I can usually detect the more obvious artifacts, but wouldn't characterize my ears as being anything near "golden". It might not quite be as critical, but I can't really hear all that much above 17 kHz.
