It's not totally accurate to say that a tuba is in C. As the others mentioned, tubas do come in different keys (typically BBb, CC, Eb, and F), but they play concert pitch whenever using bass clef music. In other words, when you play a C (open on a CC tuba, 1+3 or 1 on a BBb tuba, 1+2 on an Eb tuba, or 1+3 or open on an F tuba), it is the same pitch as C played on a piano.
You are clearly playing on a BBb tuba, so that the BBb fingering chart is what you have learned. Valve combinations for the same notes would be different for tubas in other keys.
