No it isn't. That's just definitionally incorrect.
the value of labor to a capitalist is the revenue it allows the capitalist to acquire minus the non-labor expenses (i.e. not the wage itself) associated with employing that labor. and so we will see that
profit = income - expenses
is mathematically equivalent to "Profit is the difference between the value produced by employees and what those employees are paid."
income = revenue generated by workers using the tools at their disposal (which require maintenance or replacement)
expenses = labor costs + capital costs (the maintenance and replacement of the tools/technology/etc.) + rent on the land or whatever else
so,
profit = revenue generated by workers using the tools at their disposal - labor costs - capital costs - rent and other necessary expenses
the value of the labor to the capitalist = revenue generated by workers using the tools at their disposal - capital costs - rent and other necessary expenses
you can probably see what's coming next
profit = value - labor cost (i.e. wages; compensation to the employees)
or to put it another way, profit is the difference between the value produced by employees and what those employees are paid.
