No, no son lo mismo. (No, they aren't the same.)
The verb you're talking about is
ir (to go).
Here is the present tense conjugation of the verb:
yo voy
tú vas
usted va
él va
ella va | nosostros vamos
vosotros vais
ustedes van
ellos van
ellas van |
Vamos is the first person plural form, and means 'we go' or 'we are going'. It can also mean
we will go. In Spanish, the present tense can imply what we think of as the future tense.
Here is the future form of the same verb:
yo iré
tú irás
usted irá
él irá
ella irá | nosostros iremos
vosotros iréis
ustedes irán
ellos irán
ellas irán |
Note that
iremos is the 1st person plural in this instance. It means
we will go. So,
vamos and
iremos can be interpreted to mean the same thing.
