I have a file that should be about gene expression but I really don't understand what is the meaning of this data, where are the values of gene expression?

here is column 1 through 6

#rnaseq/SNPID   hg19Location    Gene    TCGA-BH-A0C0-01A    TCGA-A2-A3XY-01   TCGA-XX-A89A-01A
rnaseq  -   ?|100130426 0.0000  0.0000  0.0000
rnaseq  -   ?|100133144 7.8666  9.6884  22.3240
rnaseq  -   ?|100134869 4.9246  24.2737 27.2744
rnaseq  -   ?|10357 104.5500    213.7269    64.1427
rnaseq  -   ?|10431 1174.0521   973.0534    722.7208
rnaseq  -   ?|136542    0.0000  0.0000  0.0000
rnaseq  -   ?|155060    141.6172    448.0890    376.4761

rnaseq  -   ?|280660    0.0000  0.0000  0.0000

From the second line I can assume that

#rnaseq/SNPID : rnaseq 
hg19Location|Gene: ?|100133144 [looks like ENTREZ id]
TCGA-BH-A0C0-01A: 7.8666 
TCGA-A2-A3XY-01: 9.6884  
TCGA-XX-A89A-01A: 22.3240

The values represents normalized expression values for individual TCGA samples.
