ICMP Results inaccurate

Hi so im noticing the ping results are not accurately showing the correct ping. is this something to do with my phone? I'm testing  on a samsung galaxy S10+ ,   

int ping = ((int) result.getAverageTimeTaken());
                        Logg.write("IP : " + ip + " Ping: " + ping);

for an IP im supposed to get 210ms im getting 98ms ?? is this normal , how could i fix it?
