Budgeted cost vs Standard cost

Budgeted cost for Product X and Y:
Product X = (200 x $20) = $4000
Product Y = (120 x $25) = $3000
Total cost = $7000

Actual cost for Product X and Y:
Product X = (190 x $22) = $4180
Product Y = (150 x $24) = $3600
Total cost = $7780

Standard cost for Product X and Y:
Product X = (190 x $20) = $3800
Product Y = (150 x $25) = $3750
Total cost = $7550

Is it true that Budgeted cost is what we expect the cost to be in the future which we then compare with the actual cost to see the difference between what we expected and what we actually paid [correct?]

But Standard cost is what we expect the cost to be in the future that each unit is budgeted to take
by taking actual units which we then compare with the actual cost to see the difference between what we expected and what we actually paid [correct?]

But Sir I don’t get the standard cost because I had to search for this but did not get the right understanding about it.

Is it correct that budgeted cost is the Total Budgeted cost that we expect to be in the future; While standard cost is the each unit cost that is budgeted to take?

The difference between them is the total cost and per unit cost? That is why when we calculate standard cost we need to take actual units and multiply that by the budgeted per unit cost?

Lastly please tell me what is the difference between the Total Budgeted cost of $7000 and the Total Standard cost of $7550 that is calculated above from your point of view? I mean what do you understand by that?
