Yes if you shield coins they are anonymous (on chain they are transferred to a one time use address and then swept into the main smart contract holding all funds). If you unshield the coins, they will show coming from the smart contract mixed with everyone else’s funds. However, if you deposit a very specific amount like 1.82762 and then later withdraw 1.82762 it will be very easy to figure out it was you.
Unshielding is extremely expensive so price a withdraw before going forward with your plans. Incognito can be used as a mixer but it’s not cheap and it is not the desire of the developers to be simply a mixer.
Your post is a bit off topic here to the title, so maybe check out some other threads if you want to learn more about this aspect.
