So, this makes the query result for underrepresented phonemes became less accurate. But the result overrepresented phonemes are still somewhat accurate. Here are the overrepresented phonemes in language with ejectives:

Phoneme Frequency  Frequency  Difference 
        In Subset  In All
kʼ      94.97      9.41       85.55
tʼ      72.96      7.23       65.72
pʼ      69.81      6.92       62.89
t̠ʃʼ     69.81      6.92       62.89
tsʼ     51.57      5.11       46.46
ʔ       85.53      45.95      39.59
ʃ       76.10      41.52      34.58
qʼ      32.70      3.24       29.46
kʷʼ     25.79      2.56       23.23
t̠ʃʰ     29.56      6.86       22.70
x       42.14      19.89      22.25
q       30.19      8.48       21.71
h       90.57      69.01      21.55
kʰ      38.99      17.77      21.23
ɬ       27.04      5.99       21.06
χ       25.79      6.48       19.30
pʰ      35.85      17.21      18.64
tʰ      30.82      13.28      17.54
ts      44.03      26.68      17.34
t̠ʃ      67.30      50.75      16.55

I think one of the thing that can be gleaned from this, is that an ejective language tend to have /ʃ q ɬ/
